Enable console debugging and add debug statements

- Enable console logging in vite.config.ts:
  - Set drop_console to false
  - Disabled pure_funcs stripping for console.log
  - Changed esbuild to only drop debugger, keep console

- Add debug logging to auth-gate.ts:
  - Log setAuthInitialized calls

- Add debug logging to useSavedStations.ts:
  - Log hook invocations
  - Log query function execution and results
  - Added retry configuration

- Add debug logging to StationsPage.tsx:
  - Log component renders
  - Log useSavedStations result state

These logs will show us what's happening with auth initialization and
query state transitions that are causing the React DOM removeChild error.
