feat(routes-f): swift/bic code validator

[davedumto]

Summary

Validate SWIFT/BIC bank codes by structure and known country codes.

Requirements

• POST { bic }
• Validate 8 or 11 char format (bank, country, location, branch)
• Bundle ISO country code list inside folder
• Return { valid, bank_code, country, location_code, branch? }
• Tests cover 8-char and 11-char BICs

Scope Constraint - READ BEFORE STARTING

All files for this task must live inside app/api/routes-f/. This includes the route handler, helpers/utilities, types, and tests. Do NOT modify, import from, or add files to lib/, utils/, types/, components/, or anywhere else outside app/api/routes-f/. If you need shared logic, duplicate it inside your subfolder. Keeping everything scoped to this folder is intentional - it keeps these tasks independent and mergeable in any order.
