Fix project manager display at small window sizes

- Don't use minimum size for project order/filter controls.
  This also allows the filter field to become longer at large
  window sizes.
- Hide the loading label instead of changing its opacity.
  This causes a reflow during loading, but this is preferable to having
  the UI overflow.
- Hide the About button on Android as it will spawn a dialog that's
  too large to be closed on most screens.
- Hide the language dropdown on Android as it doesn't work correctly.

This allows the project manager to be displayed correctly at much
lower window sizes than previously.
