Improvements:

• OSS notices: Notice configuration now comes from a static, cacheable repository file with a bundled disabled fallback and deterministic rollout assignment, instead of calling PostHog's feature-flag evaluation API. This keeps notices fail-safe when the remote config is unavailable and removes the PostHog feature-flag request from notice evaluation (#7185)
• Vector Stores: RedisDBConfig now uses Pydantic's native extra="forbid" handling for unknown fields instead of a custom model validator, preserving strict validation while returning standard Pydantic errors (#7089)
