Issue:
-------
After the fix:
https://github.com/odoo/odoo/commit/f1557211d9e7f83761bb36e4800e4c2f62b234c5 we can't create a child menu for a mega menu or a menu can't be a mega menu when there's an existing child menu except the case of top level menu i.e; (url: /default-main-menu) and that menu will have no parent_id obviously...

Now, as per the above pr conditions the top level can be set as mega menu since it has no parent id. And in version 17.3 in the pr https://github.com/odoo/odoo/commit/47af533e9f5f721b63570d3b301951f3855384a1 a 'Jobs' menu is being created and its parent_id refers to that top level menu which we have set as mega menu. And when the records gets validated during migration the database will get blocked.

Solution:
-----------
Restrict the user by throwing the same user error, when checking/selecting the top level menu as mega menu since it has existing child menus.

Step to reproduce:
-----------------------
1. Create a database in version 17.0 with 'website_hr_recruitment' installed.
2. Go to website menus, set a top level menu(/default-main-menu) as mega menu.
3. Migrate the database to version 18.0 or more.

l10n_vn_pos_symbol carries groups='base.group_system,point_of_sale.group_pos_manager', but _prepare_invoice_vals reads it while an ORDINARY salesperson closes an order: _process_saved_order calls _generate_pos_order_invoice as the acting user, with no sudo anywhere on the way. So on a Vietnamese POS with auto-send to SInvoice enabled, a user in point_of_sale.group_pos_user alone hit

  Access Denied by ACLs for operation: read, model: pos.config, fields: l10n_vn_pos_symbol

and the order never finished syncing - the receipt screen's Done button stayed disabled and the checkout dead-ended.

This is reachable from the module's own test suite, which is what makes it more than theoretical: point_of_sale's start_pos_tour logs in as `pos_user` (group_pos_user, NOT group_pos_manager - that is `pos_admin`), so test_l10n_vn_edi_pos_refund_reason_tour exercises exactly the unprivileged path.

Reading the config as sudo is the right resolution rather than widening the field's groups: the salesperson is never shown the symbol or allowed to change it, it is only stamped onto the invoice their own sale produces, which is what a per-POS configuration field is for. Both symbols are read through the same sudo recordset so the company-level fallback keeps working identically.

Reproduced and verified on v18_full (5-repo addons path):
  before - FAILED: [13/36] Tour L10nVnEdiPosRefundReasonTour -> "go to next screen from
           receipt"; 1 failed, 0 error(s) of 1 tests
  after  - tour succeeded for both tours in the class; 0 failed, 0 error(s) of 2 tests,
           and no ACL line left in the log

mark_urbanpiper_prep_order_as_printed() raised ValueError when the
'urbanpiper_printed' flag was already set, to stop the same order from
printing its preparation ticket twice (https://github.com/odoo/enterprise/pull/103894,
Task-5353283).

Accepting an UrbanPiper order fires this RPC from two places for the
same order: synchronously from TicketScreen, and again via the
DELIVERY_ORDER_COUNT bus notification the accept flow itself
broadcasts. Under load, both requests race for the row lock; Odoo's
retrying() replays the loser on lock contention, and by the time it
replays the winner has already committed, so the loser hits the
already-printed branch and raises. The raise is an unhandled
ValueError, so it surfaces as a 500 and fails any tour that accepts
an order (test_frontend.py, test_order_receipt.py),
intermittently and CI-timing-dependent only.

The only caller (pos_store.js: _sendDeliveryOrderForPreparation)
already wraps the RPC in try/catch and treats a caught exception
exactly like a falsy return value: either way it just skips sending
the ticket to preparation. No other code reads or writes
urbanpiper_printed, and no webhook path calls this method, so
returning False is behaviorally identical for every real caller and
safe to make the default.

This also removes the mark_urbanpiper_prep_order_as_printed_patch
monkeypatch added alongside the original raise in test_01_order_flow:
it existed solely to swallow this exact ValueError for that one tour,
which is no longer needed now that the method itself is idempotent.

Since `company_id` on `worksheet.template` changed due to this a973d7d from a Many2many to a Many2one field.

For example, in v17, a single worksheet template linked to 3 companies via the m2m field was returned as 1 record when opening Design Template. After the upgrade in v18, company_id became m2o, and the same data is split into 3 separate records (one per company).

When trying to add a customization via Studio, the search [fetches](https://github.com/odoo/enterprise/blob/18.0/worksheet/controllers/main.py#L12) records based on the model set on the worksheet. In the new version, Studio
[creates](https://github.com/odoo/enterprise/blob/18.0/worksheet/models/worksheet_template.py#L112)
 a new model, but for existing records the
model is the same across the 3 worksheet records tied to the same template. This causes the search to match all 3 records and raise a SingletonError.

Steps to Reproduce:
1. Configure Payment Term (Accounting > Configuration > Payment Terms) containing multiple installments.
2. Create a Customer Invoice with this Payment Term.
3. Post the invoice.
4. Register a payment and fully reconcile one of the installments.
5. Navigate to the customer's Follow-Up Report (Accounting > Reporting > Partner Ledger > Report: Follow-Up Report).
6. Navigate to remaining open installment/account move line for that invoice.
7. Turn On or Off the No Follow-Up toggle for the invoice.

An error occurs when enabling or disabling the No Follow-Up toggle.

Issue:
Enabling or disabling the No Follow-Up toggle on a remaining open installment in the Follow-Up Report raises a server error when the invoice contains multiple installments and one or more installments are already fully reconciled.

Root Cause:
The Follow-Up Report only loads and sends non-fully reconciled account move lines from the JavaScript side through all_line_ids. In action_toggle_no_followup(), when the selected line belongs to an invoice, the code retrieves all receivable/payable lines of the invoice, including fully reconciled installments:

```
move.line_ids.filtered(
    lambda line: line.account_type in ('asset_receivable', 'liability_payable'),
)
```

The method then attempts to map every receivable/payable line to a report line ID using aml_id_to_line_id. Since fully reconciled installments are not present in all_line_ids, they are missing from the mapping dictionary, causing a KeyError when accessing:

`aml_id_to_line_id[line.id]
`

Fix:
Restricted the impacted lines to those present in the report by adding a check that the account move line exists in aml_id_to_line_id before performing the mapping:

```
lambda line: line.account_type in ('asset_receivable', 'liability_payable')
             and line.id in aml_id_to_line_id
```
