feat: Refactor uTLS & Multiplex Support, Node Status Push Optimization

- Server/ServerSave/Server.php: Unified utls and multiplex schema, validation, and defaults for vmess/vless/trojan/mieru protocols, enabling more flexible protocol configuration.
- Protocols (SingBox/ClashMeta/Shadowrocket/Stash/General): All protocol generators now support utls (client-fingerprint/fp) and multiplex options. Removed getRandFingerprint, replaced with getTlsFingerprint supporting random/custom fingerprints.
- Helper.php: Refactored TLS fingerprint utility to support object/string/random input.
- ServerService: Abstracted updateMetrics method to unify HTTP/WS node status caching logic.
- NodeWebSocketServer: Improved node connection, status push, and full sync logic; adjusted log levels; clarified push logic.
- ServerController: Reused ServerService for node metrics handling, reducing code duplication.
- Docs: Improved aapanel installation docs, added fix for empty admin dashboard.
