fix: repair broken tests and remove unused dependencies

Test fixes:
- Fix app_session.py to use 'textual-webterm' package name (not 'textual-web')
- Fix CLI version test to not hardcode version number
- Fix static path test to not use removed Path._flavour attribute

Removed unused dependencies:
- xdg
- msgpack
- httpx

All 209 tests pass with 86% coverage.
