refactor: improve logging levels and environment configuration

- Fix logging levels: change verbose debugging from info to debug level
  - TestView: component mounting, boot-time config, URL flow testing
  - main.capacitor.ts: deeplink processing steps and router state
  - HomeView: API call details, component state updates, template rendering

- Remove redundant environment variable override in vite.config.common.mts
  - Environment loading via dotenv works correctly
  - Manual override was defensive programming but unnecessary
  - Simplifies configuration and reduces maintenance burden

- Add comprehensive Playwright timeout behavior documentation
  - README.md: detailed timeout types, failure behavior, debugging guide
  - TESTING.md: timeout failure troubleshooting and common scenarios
  - Clarifies that timeout failures indicate real issues, not flaky tests

- Fix TypeScript configuration for .mts imports
  - tsconfig.node.json: add allowImportingTsExtensions for Vite config files
  - Resolves import path linting errors for .mts extensions

All changes maintain existing functionality while improving code quality
and reducing log noise in production environments.
