Improve ProgramDetailModal layout per feedback

- Move channel name/number into modal header title bar (was empty after removing duplicate title)
- Remove channel logo from modal (didn't fit well)
- Remove custom background color override, inherit from Mantine dark theme for consistency with VOD/Series modals
- Fix wrong channel shown in modal: pass channel directly from renderProgram instead of re-looking up by tvg_id
- Clean up unused imports (getChannelLogoUrl, Image/Group no longer needed in title)
