fix: resolve type errors and migrate pnpm settings to pnpm-workspace.yaml

- Move pnpm.onlyBuiltDependencies/overrides from package.json to pnpm-workspace.yaml (clears pnpm WARN)
- Allow useServerAction run() to accept actions returning void
- Make adminAction/authAction input optional so no-schema actions can be called without args
- Return ActionResult from updateBcPage
- Fix categoryPageMap value type (number | undefined)
- Declare DbService.queryCount field
- Use definite assignment for release in withFurniDataLock
- Narrow pair type in theme-contrast test
