[IMP] account_peppol, account_edi_ubl_cii: Make the error message more accurate when sending via Peppol.

Core18.0account_peppolaccount_edi_ubl_ciiMEDIUM

This update clarifies error messages when sending invoices via Peppol. Previously, users received a generic 'no VAT' error, which was confusing. Now, the system accurately identifies the missing Peppol VAT information (like a company registry number), guiding users to correct the data and ensure successful transmission.

Original PR description

When a user sends a move via Peppol to a customer that has a VAT number set but not a Peppol endpoint, we show the user a generic error ("no VAT").

This makes the user confused, as he already filled the VAT field of his customer, It's the Peppol VAT that is missing (it could be: Belgian Company Registry, France SIRET, ...etc, depending on the customer's country)

This PR makes the error message more accurate by showing exactly the missing required field.

[FIX] project_enterprise: fix gantt unavailabilities for flexible employees

PR #113247

Enterprise18.0project_enterprise

This update fixes an issue where flexible employees were incorrectly shown as unavailable in the Project Gantt chart. The change ensures that flexible employees without scheduled leaves are not grayed out, aligning the Gantt chart with their actual working hours. This improves the accuracy of project timelines.

Original PR description

Steps to Reproduce
---
- Assign a flexible working schedule to an employee (no leaves)
- Open Project > Tasks > Gantt view grouped by Assignee
- The employee's weekends and off-hours are grayed out

Current Behavior
---
Flex employees with no approved leaves in the viewed date range have incorrect grayed-out days in the Project Gantt view.

Expected Behavior
---
Flex employees should have no grayed-out days except approved leaves and public holidays.

Issue
---
When a flex employee has no leaves in the viewed period, `_get_unavailable_intervals()` returns an empty dict for that resource. `_gantt_unavailability()` then falls back to `company_leaves`, producing incorrect gray intervals. The same case is already handled in `planning` (ref PR), but `project_enterprise` was not covered.

Fix
---
Add a guard in `_gantt_unavailability()` to return no unavailabilities for flexible resources absent from `leaves_mapping`.
