Add missing component and hook tests, raise coverage thresholds

13 new test files for untested components (color-palette, player-management,
stat-block, settings-modal, export/import dialogs, bulk-import-prompt,
source-fetch-prompt, player-character-section) and hooks (use-long-press,
use-swipe-to-dismiss, use-bulk-import, use-initiative-rolls). Expand
combatant-row tests with inline editing, HP popover, and condition picker.

Component coverage: 59% → 80% lines, 55% → 71% branches
Hook coverage: 72% → 83% lines, 55% → 66% branches
