* fix: Add removePorts keyGenerator to all IP-based rate limiters Six IP-based rate limiters are missing the `keyGenerator: removePorts` option that is already used by the auth-related limiters (login, register, resetPassword, verifyEmail). Without it, reverse proxies that include ports in X-Forwarded-For headers cause ERR_ERL_INVALID_IP_ADDRESS errors from express-rate-limit. Fixes #12318 * fix: make removePorts IPv6-safe to prevent rate-limit key collisions The original regex `/:\d+[^:]*$/` treated the last colon-delimited segment of bare IPv6 addresses as a port, mangling valid IPs (e.g. `::1` → `::`, `2001:db8::1` → `2001:db8::`). Distinct IPv6 clients could collapse into the same rate-limit bucket. Use `net.isIP()` as a fast path for already-valid IPs, then match bracketed IPv6+port and IPv4+port explicitly. Bare IPv6 addresses are now returned unchanged. Also fixes pre-existing property ordering inconsistency in ttsLimiters.js userLimiterOptions (keyGenerator before store). * refactor: move removePorts to packages/api as TypeScript, fix import order - Move removePorts implementation to packages/api/src/utils/removePorts.ts with proper Express Request typing - Reduce api/server/utils/removePorts.js to a thin re-export from @librechat/api for backward compatibility - Consolidate removePorts import with limiterCache from @librechat/api in all 6 limiter files, fixing import order (package imports shortest to longest, local imports longest to shortest) - Remove narrating inline comments per code style guidelines --------- Co-authored-by: Danny Avila <danny@librechat.ai>
