fix(android): make pairing code fit/visible on all screen sizes

Browse source 
Reported on a Pixel 10: the pairing code wasn't visible. The provisioning screen
was a non-scrolling vertical stack, and when the pairing section appeared below
the server-URL + Connect controls, the fixed 64sp code got pushed off-screen on
short/landscape phones (and could clip horizontally on narrow widths).

- Wrap the screen in a ScrollView (fillViewport) so content is always reachable.
- pairingCodeText now auto-sizes (autoSizeTextType=uniform, 24-96sp, single line,
  match_parent width) so it fills the width and never clips - phones, TVs, sticks.
- Hide the server-URL section + Connect button once paired so the code gets the
  full screen.

Compile-checked + signed APK builds. Needs on-device confirmation (Pixel 10 /
onn stick) that the code is now visible.
