When the AI agent switched from another view to a pivot view, the pivot view
could crash or open without any active measures.

The AI controller patch applies the agent's adjustments upon receiving the
`APPLY_AI_ADJUST_MODEL` bus event. However, the event could be processed while
the pivot model was still executing `_loadData()`.

In that case, the following sequence occurred:

* `_loadData()` started and awaited.
* The controller patch was executed.
* The patch called `toggleMeasures()`.
* `toggleMeasures()` waited for `_loadData()` to complete.
* `_loadData()` finished and updated the metadata with the available measures.
* `toggleMeasures()` resumed and wrote back the metadata snapshot it had taken
before waiting.

Since `toggleMeasures()` operates on a snapshot of the metadata, the measures
populated by `_loadData()` were lost when the snapshot replaced the current
metadata, leaving the pivot model without its `measures` metadata and causing
the view to crash.

Prevent this race condition by waiting for the pivot model initialization to
complete before applying the AI adjustments.

Also preserve the default active measures when the AI agent does not explicitly
request any measures instead of clearing them and opening an empty pivot view.

`_prepare_edi_vals` always called `_get_formatted_payment_values()`, adding an EDI-Paiement (telereglement) block to the T-IDENTIF of the 3310CA3, regardless of whether the company owes VAT or is in a credit position.

Steps to reproduce:
- French company in a VAT credit position, requesting a refund.
- Fill a bank account line, the account to receive the refund and send the VAT report to the DGFiP.

Current behaviour:
The DGFiP returns a negative acknowledgement on the CA3 interchange: "Telereglement 1 rejete: Montant telereglement absent ou invalide. Code erreur : 018", even though the declaration itself is accepted.

The wizard's bank account lines are reused for two opposite purposes: the account to debit when VAT is due, and the account to credit when a refund is asked. `_get_formatted_payment_values()` builds a payment order from them unconditionally, so a telereglement for the credit amount is emitted in the refund case. A telereglement is invalid when no VAT is due, hence error 018. A return nets to either a payment or a credit, never both, so the two cases are mutually exclusive.

This commit guards the call with `self.is_vat_due`, so the telereglement is only generated when the company actually owes VAT. The VAT-due flow is unchanged.

* = din5008_account_followup, din5008_industry_fsm

**Steps to reproduce:**

* Install the **Germany - Accounting** (`l10n_de`) module (which pulls in `l10n_din5008`)
* Set the document layout to **DIN 5008** and generate any PDF report (invoice, quotation, purchase order, etc.).

**Observed behavior (date format):**

* All dates in the information block (Invoice Date, Due Date, Delivery Date, Order Date, etc.) are rendered in `yyyy-mm-dd` format instead of the expected `dd.MM.yyyy` format used in DE, AT, and CH.

**Cause (date format):**

* All `t-options="{'widget': 'date'}"` directives across the DIN 5008 template family rely on the active user's language locale for date formatting. If the user language is not `de_DE`, dates render in the locale's default format (e.g. `yyyy-mm-dd` for `en_US`).

**Fix (date format):**

* Add `'format': 'dd.MM.yyyy'` explicitly to all `t-options` date widgets across all DIN 5008 report templates (`l10n_din5008`, `l10n_din5008_sale`, `l10n_din5008_purchase`, `l10n_din5008_sale_subscription`, `l10n_din5008_repair`, `l10n_din5008_account_followup`, `l10n_din5008_industry_fsm`).
* This is correct for all three countries using DIN 5008 (DE, AT, CH), which all follow the `dd.MM.yyyy` convention.

The PstlAdr block written into pain.001 files never contains the
partner's state/province nor the second street line, even when they
are set on the record: _get_all_addr() now returns them, but
_get_PstlAdr() also needs to write them out. Some North American banks
reject wire transfers whose beneficiary address lacks the
state/province, so those payments fail regardless of how complete the
vendor record is.

Emit CtrySubDvsn when the address has a state, before Ctry as required
by the element order of the PostalAddress schema, and append street2
to the street address line.

Steps to reproduce:
- Install Accounting and enable a generic ISO 20022 payment method on
  a bank journal
- Create a vendor located in the US or Canada with a complete address,
  including the state and a second street line
- Register a vendor payment, add it to a batch and generate the
  pain.001 file
- The creditor PstlAdr has no state/province, and its street line only
  carries the first street field: the street2 part is dropped


Requires odoo/odoo#282518, which makes _get_all_addr() return the state and street2.

_get_all_addr() feeds the postal address block of generated pain.001
payment files, but does not return the partner's state nor the second
street line. The beneficiary state/province and street complement
(suite, unit, ...) therefore never appear in the generated file, even
when they are set on the partner, and there is no way to fix it from
the record. Some North American banks reject wire transfers whose
beneficiary address lacks the state/province, so those payments fail
regardless of how complete the vendor record is.

Return the state code and street2 alongside the other address
components, from the partner for the base implementation and from the
employee private address for the hr one, so the payment engine can
write them in the PstlAdr block.

Steps to reproduce:
- Install Accounting and enable a generic ISO 20022 payment method on
  a bank journal
- Create a vendor located in the US or Canada with a complete address,
  including the state and a second street line
- Register a vendor payment, add it to a batch and generate the
  pain.001 file
- The creditor PstlAdr has no state/province, and its street line only
  carries the first street field: the street2 part is dropped

Steps to produce:
---
- Install the `Sales` module.
- In Settings, enable `Automatic Invoice`.
- Also enable the Demo payment provider.
- Create a sale order with a total of `800` and confirm it.
- Generate a payment link for `200` from the gear icon and pay it.
- Generate a second payment link for `300` and pay it.
- Generate a final payment link for the remaining `300` and pay it.

Issue:
---
- After the first payment (200), an `invoice of 200` is created. Correct.
- After the second payment (300), an` invoice of 500` is created instead of 300.
- After the third payment (300), an `invoice of 100` is created instead of 300.

Root cause:
---
- The down payment invoice uses `order.amount_paid`, the cumulative sum of all transactions on the order, instead of the amount of the latest payment. This causes invoices to be sized off the running total instead of the individual payment delta.

Fix:
---
- Compute the invoice amount as `order.amount_paid - order.amount_invoiced` (the unpaid) instead of passing the cumulative `amount_paid` directly.
