fix: truncate long contact name in favorites tile (WT-1051)

[SERDUN]

Overview

WT-1051 reported that a long contact name in the Contacts list was not truncated and overflowed, breaking the list layout. The Contacts tabs were already fixed by WT-1537 (ContactTile now wraps the name in an Expanded with maxLines + TextOverflow.ellipsis), but the Favorites tile had the same defect left over.

FavoriteTile rendered the name and the label/number subtitle through a plain ListTile with no line or overflow constraint, so a long favorite name still wrapped over multiple lines.

Changes

• favorite_tile.dart: add maxLines: 1 + overflow: TextOverflow.ellipsis to the title (both presence and non-presence branches) and to the subtitle, matching the truncation behavior of ContactTile.

Testing

• dart format --set-exit-if-changed clean.
• dart analyze on the file: no issues.
• Pre-push hooks green (flutter analyze + full test suite, 747 tests).
