♻️ refactor: extract server into apps/server + root namespaces into packages (#14949)

* ♻️ refactor(server-deps): extract envs/trpc/config/locales/business-server into packages

* ♻️ refactor: relocate src/server backend modules to apps/server package

Rebuilt on current canary: git mv the 8 server subtrees (services, routers,
modules, globalConfig, utils, runtimeConfig, workflows, featureFlags) into
@lobechat/server, with @/server/* dual-path alias, database vitest aliases,
and instrumentation import fixup.

* 📝 docs(skills): update src/server path refs to apps/server/src after relocation
