### Bug

`odoo.tools.date_utils.float_to_time` builds the minutes with a rounding step:

```python
return time(int(integral), int(float_round(60 * fractional, precision_digits=0)), 0)
```

When the fractional part of the hour is high enough, `round(60 * fractional)`
rounds up to a full **60**, and `time(hour, 60)` is invalid:

```python
>>> float_to_time(16.9959)
ValueError: minute must be in 0..59, not 60
>>> float_to_time(8.999)
ValueError: minute must be in 0..59, not 60
```

Any hours value whose fractional part is ≥ ~0.9917 hits this — which happens
easily with computed/aggregated work-hour floats.

### Fix

Carry the rounded-up minute into the hour, and return `time.max` when that carry
reaches the end of the day (mirroring the existing `hours == 24.0` case):

```python
if minute == 60:
    hour += 1
    minute = 0
if hour >= 24:
    return time.max
```

`float_to_time(16.9959)` now returns `time(17, 0)`, `float_to_time(23.9959)`
returns `time.max`, and regular values are unchanged.

Adds `TestFloatToTime` in `test_date_utils.py` covering the carry, the
end-of-day carry, and regular values.

The following commit resets qty_invoiced to zero on sale order lines paid by a POS order when that order is refunded.
https://github.com/odoo/odoo/commit/ac39aa4f68dfc77011c39e468e3f60e0338a3c69

However, it does not handle the sale order line created for a refunded POS down payment. That line keeps `qty_invoiced` = -1, which causes the refunded amount to be included again when settling or invoicing the sale order.

Steps to reproduce:
- Create a sale order.
- Pay a down payment through the POS.
- Refund the down payment order from the POS.
- Settle the remaining amount from the POS or invoice the sale order from the backend.

Result:
- The generated invoice includes the sale order total plus the refunded down payment.
- Sale order `amount_invoiced` will be the down payment amount.

Fix:
- Delete the refunded downpayment to match the sale flow.
- Include refunded down payments in the amount_invoiced computation.

When recomputing overtime, attendances overlapping the affected day are retrieved based on their check-in and check-out.

An attendance whose check-out is exactly at the start of the following day is currently considered to overlap that day because the domain uses an inclusive lower bound on `check_out`.

This can cause overtime from the previous day to be recomputed using an incomplete set of attendances.

### Steps to reproduce:

* Configure an employee with a daily quantity overtime rule based on the expected hours from the contract.
* On the first day, create multiple attendances, with the last one ending exactly at midnight.
* Ensure the total worked hours on that day result in overtime.
* On the following day, create another attendance.
* Observe that recomputing the second day's overtime also retrieves the attendance ending at midnight.
* The previous day's overtime is then recomputed without the other attendances from that day, resulting in an incorrect overtime value.
* Regenerating the overtime ruleset restores the correct value.

For example, with 8.4 expected hours:

```
Day 1:
    09:30 - 11:30
    14:30 - 18:19
    21:00 - 00:00

Day 2:
    create/update an attendance
```

The `21:00 - 00:00` attendance is incorrectly included in Day 2's recomputation because its check-out equals the start of Day 2. The other Day 1 attendances are not included, so Day 1 is recomputed from only 3 hours of work.

To fix the issue we treat `check_out` as an exclusive interval boundary when determining overlap. An attendance ending exactly at the start of a day does not overlap that day, while attendances actually crossing midnight continue to be included.

Issue:

- DATEV does not support multiple foreign currencies on a single journal line.
- This can occur when reconciling a bank transaction where:
  - the payer uses one currency (C1),
  - the bank journal is held in another currency (C2),
  - the company uses a third currency (C3).
- The existing export logic could not represent the bank liquidity and
  foreign AR/AP currencies separately in such cases.

Fix:

- Detect 3-currency cases from bank statement transactions and their
  liquidity line.
- Use the DATEV clearing account (1360 SKR03 / 1460 SKR04) to split the
  transaction into two logical legs:
  - Bank → Clearing (bank journal currency)
  - AR/AP → Clearing (payer currency)
- Emit the liquidity leg only once when multiple foreign AR/AP lines are
  reconciled against the same bank transaction.
- Keep regular 1- and 2-currency transactions on the existing export path.

Impact:

- Correctly represents 3-currency bank settlements in DATEV.
- Keeps each exported line in a single foreign currency.
- Leaves manual entries and payment transactions outside this specific
  handling, as the scenario is specific to the bank liquidity line.

**Steps to reproduce:**
- Install Accounting, Sales and l10n_pe_edi
- Switch to a Peruvian company (e.g. PE Company)

- Create a SO:
  * Customer: [a Peruvian customer]
  * Order Lines:
    | Product | Quantity | Unit Price |  Taxes  | 
    | ------- | -------- | ---------- | ------- |
    |   any   |   3.00   |   123.50   | VAT 18% |
    |   any   |   2.00   |  27.544216 |  0% Ina |
    |   any   |   1.00   |  43.490867 |  0% Exo |

- Confirm the SO
- Create a 40% down payment
- Confirm the down payment
- Process it to sent it to Peru UBL 2.1

**Issue:**
The following error message is returned by the OSE:
`3272|La base imponible a nivel de línea difiere de lainformación consignada en el comprobante - Detalle: xxx.xxx.xxx ticket : 20260000000000221633458 error: Error en la Linea Nro. :1. : 3272 (nodo: "cac:TaxSubtotal/cbc:TaxableAmount" valor: "148.20")`

**Cause:**
In the XML, one line has 148.19 for "cbc:LineExtensionAmount", but 148.20 for "cac:TaxSubtotal/cbc:TaxableAmount".
The issue is coming from the fact that "base_amount_currency" is used instead of "total_excluded_currency" for the computation of "cac:TaxSubtotal/cbc:TaxableAmount".

**Issue 2:**
When a tax is impacting the base amount of a following tax, its tax amount is not taken into account in "total_excluded_currency".
