The appointment styling was updated to use the newer Bootstrap color contrast method. This helps keep text readable after the Bootstrap 5 migration and prevents visual inconsistencies in appointment pages.

This commit properly convert `color-yiq` SCSS function calls by
replacing them with `color-contrast`.

This update fixes a visual flicker when viewing or editing approval types. It makes the approvals interface feel smoother and reduces distraction for users managing approval workflows.

Before this PR, importing an .OFX file from BNP failed because the account number format is not the same. This is a problem on BNP's side but it is blocking for our clients and needs to be fixed. This commit fixes this by checking that the account number corresponds to a specific part of the IBAN (for France only).
