fix(roaming,settings): theme colors for night mode; unclamp cards; brand title and APK name

Three detail fixes plus branding, per user review:

1. Night mode visibility (roaming page): hardcoded reference blues
   (#01DDFF/#0BACF1) collapse to black under the red ColorMatrix
   filter (R channel only), making the page unreadable. Replace ALL
   colors with MaterialTheme.colorScheme (background/surface/
   surfaceVariant/onSurface/onSurfaceVariant/primary/error). GPS
   status dots become themed circles (primary/error) so they survive
   the red filter; red marker keeps the original pnt drawable.

2. Settings cards unclamped:
   - OtherCard: fixed height(268.dp) squeezed the last toggle row
     (spacing 42/42/42/15px on device); drop the fixed height.
   - CardCredits: same 268dp + SpaceBetween overflowed, gluing the
     last thanks entry to the warranty line; drop fixed height, use
     spacedBy(8.dp) and insert 24dp before the warranty text.

3. Branding:
   - Settings top title: "Look4Sat v%s" -> "Look4Sat Pro v%s" (en/tr);
     title Text no longer marquees and wraps instead (heightIn(min=48)).
   - APK asset name: look4sat-<ver>.apk -> Look4Sat-Pro-<ver>.apk.
   - What's-new dialog (pass_whatsnew_message) rewritten in all three
     locales (en/zh/tr) with this release's changes; zh gets its own
     localized title "Look4Sat Pro 更新内容".

Verified: roaming/settings/passes/app compile, 11 unit tests pass.
