fix(ui): resolve landscape crashes, video scaling, and input styling
- Fixed NullPointerException on rotation by syncing XML IDs in layout-land.
- Implemented split-screen layout for landscape mode (Logo Left / Form Right).
- Fixed video stretching issue with smart zoom-to-fill logic in LoginFragment.
- Applied transparent "glassmorphism" style to input fields for better UI.
- Extracted hardcoded strings to strings.xml and fixed accessibility warnings.
- Removed configChanges from Manifest to allow proper layout switching.
