CaIon 0973dc2b8f feat(security): harden account binding and password changes
Require scoped, single-use verification for account bindings and password
operations. Bind OAuth authorization and email confirmations to the initiating
session; preserve the last usable login method and audit operation outcomes.

Apply Unicode-aware password length limits, Argon2id writes with bcrypt
compatibility, and long-password encryption.
Return has_password with the existing profile SELECT without extra queries.
Reuse the existing security dialogs and add all seven locale translations.

Validation:
- Go: go test ./common ./model ./service ./middleware ./controller ./router -count=1
- DB: SQLite 3.50.4, MySQL 8.4.11, PostgreSQL 16.15; separate main/log databases
- MySQL/PostgreSQL: TEST_SECURITY_DIALECT=<dialect> with TEST_<DIALECT>_DSN,
  go test ./controller -run '^(TestSecurityAccount|TestSecurityEnrollment|TestGenerateOAuthCode|TestOAuthBind|TestTelegramOAuth)' -count=1 -v
- Web: relevant Vitest suites, bun run typecheck, targeted oxlint/format,
  bun run i18n:sync, and bun run build

Roll out dual-format readers to every instance with
ACCOUNT_PASSWORD_HASH_ALGORITHM=bcrypt before enabling Argon2id writes
and the new UI. Rollbacks must retain Argon2id and v2 envelope readers.

Relevant controls: ASVS 5.0.0 6.2.1-6.2.3, 6.2.5-6.2.9, 6.3.7, 7.4.3, 7.5.1;
this change does not assert application-wide ASVS certification.
