* feat: add BankID authentication via TIC Identity API
Integrate BankID as a login/signup method using the TIC Identity API.
Users can authenticate with BankID QR codes (desktop) or deep links (mobile),
link BankID to existing accounts, and skip TOTP MFA when BankID is linked.
Removes Step 0 (role choice) from onboarding for all users. Adds enrichment
data support for pre-filling company details from Bolagsverket during signup.

* fix: address PR review — server-side rate limit, unlink clears MFA bypass
- Add per-IP rate limit (5s cooldown) on /bankid/start to prevent
unbounded billable TIC sessions from unauthenticated callers
- Add /bankid/unlink endpoint that deletes bankid_identities AND clears
app_metadata.bankid_linked so MFA enforcement resumes after unlink
- Update BankIdSettings to call server-side unlink instead of client-side delete

* fix: move rate limiter to module scope, add BankID logo and year-end skill
