feat(api-tokens): manage multiple named tokens; add tab/section anchor URLs

Replace the single regenerable API token with a named-token list:
- New ApiToken model + service with constant-time auth matching
- Seeder migrates the legacy `apiToken` setting into a "default" row
- Security tab gets create/enable/delete UI; api-docs page links to it
- Dedicated "API Tokens" section in the in-panel docs

URL anchors now reflect the active tab/section on Settings, Xray, and
API Docs pages, so deep links like `/panel/settings#security` work.

Translations for the 8 new SecurityTab strings added across all locales.
