Partner Bank Code

This module extends the bank records already available in Odoo (the res.bank model) with two extra text fields: Bank Code and Bank Branch Code. These appear on the bank form right after the BIC field, and are also available as optional columns in the bank list view, so users can show or hide them as needed.

Business rules added by the module:

• A uniqueness check prevents saving two bank records with the same Bank Code and Bank Branch Code combination. If a duplicate is entered, Odoo blocks the save with the message "Bank and Branch Code should be unique."
• The bank's display name is automatically enriched: when a Bank Code is filled in, the name shown becomes the bank name followed by the code in brackets, for example "Bank Name [1234]". If a branch code is also present, it is added after a slash, for example "Bank Name [1234/567]".
• Searching for a bank by name also looks at the BIC, Bank Code and Bank Branch Code, so typing a code prefix finds the right bank.

No new menus or screens are created; the changes are integrated into the existing bank configuration screens. The module only depends on the base module and does not touch sales, purchases, accounting entries or contacts beyond the bank records themselves.
