* feat(admin): add IP whitelist (strict allowlist mode) (#920)
- Add enableWhitelist/whitelist fields to IpBlacklistSettings
- Implement three-layer access control: whitelist → blacklist → daily limit
- Whitelist uses exact match for IPv4/IPv6, regex for patterns
- Whitelisted IPs skip blacklist checks (trusted)
- Fail-closed when cf-connecting-ip missing under whitelist mode
- Frontend: independent whitelist toggle + empty list protection
- Backend: backward compatible (old frontends get defaults)
- E2E tests: config validation + runtime behavior
- Docs: CHANGELOG zh/en updated
Closes#920
* fix(admin): address PR review feedback on IP whitelist
- Add IPv4-mapped IPv6 (::ffff:x.x.x.x) exact match in isWhitelisted
- Include error.message in whitelist regex parse failure log
- Include actual/max size in whitelist size limit error message

* fix(admin): validate whitelist regex on save and preserve existing whitelist on partial update
- Reject invalid regex patterns in whitelist at save time to prevent runtime lockout
- Preserve existing enableWhitelist/whitelist from DB when older clients omit these fields

* fix(admin): fix fingerprint blacklist bypass when cf-connecting-ip absent, improve e2e tests
- Split checkBlacklist into checkFingerprintBlacklist (IP-independent) and checkIpAsnBlacklist
- Fingerprint check now runs before the !reqIp early-return to prevent bypass
- Add afterEach reset to config test group, extract RESET_SETTINGS constant
- Strengthen whitelist-blocks test to deterministic 403 assertion
- Add e2e tests: invalid regex rejection, non-string element rejection, fingerprint-blocks-without-IP
