Fixes for error handling, UI padding, & more (#1759)

## Description
Another collection of small individual fixes that don't warrant a full
PR:
- Better error handling for series and collection detail pages
- Better error handling on Discover search tab
- Fix issues when changing view options on card grid without reloading
the page
- Better error handling when changing the refresh rate or resolution
- Fix some nav drawer items disappearing briefly when restarting the app
- Fix that the discover search row would not clear when the query is
cleared

And some UI tweaks:
- Use consistent padding for the different customize home page sections
- Convert the "Continue watching click behavior" setting from a toggle
to choice dialog (the options & behaviors have not changed)

### Related issues
I think the error handling when changing the refresh rate might help
with #1737

### Testing
Emulator mostly

## Screenshots
N/A, UI changes are minor

## AI or LLM usage
None
