Coresaas-19.2l10n_lk_invoiceMedium

Adds support for Sri Lanka-specific tax invoice numbering and document wording so compliant invoices can be issued directly in Odoo.

This commit introduces the `l10n_lk_invoice` module to support specific tax invoicing requirements for the Sri Lankan localization.

Key features include:
* Custom Sequence Format: Implements the mandatory Sri Lankan tax invoice sequence format `YYMMM_QQQQ_XXXXX` (e.g., `26MAY_BRN01_00001`), utilizing the journal code as the `QQQQ` component.
* VAT Registration Tracking: Adds a `l10n_lk_vat_registered` boolean field to `res.partner` and `res.company`. This auto-computes based on the Sri Lankan VAT format (requiring >= 13 digits and ending in the "7000" suffix).
* PDF Report Modifications:
  * Replaces the "Invoice" title with "Tax Invoice" when both the supplier and the customer are VAT registered, AND the invoice contains taxable supplies (excludes fully exempt invoices).
  * Replaces "Delivery Date" with "Supply Date" on tax invoices.
  * Injects "Mode of Payment" into the document header when a preferred payment method is selected on a tax invoice.
* Resequencing Wizard Support: Overrides `account.resequence.wizard` to seamlessly handle Sri Lanka's specific month abbreviation formatting during mass resequencing.
