feat: add contact search to command bar

[edospadoni]

Summary

• Transform the command bar into a Spotlight-style search bar: users can type a name (or number) to search both the phonebook and local operators, navigate with arrow keys, and call with Enter
• Operators appear first in results with avatar and presence indicator, deduped against phonebook entries
• Dynamic window resize via new COMMAND_BAR_RESIZE IPC event, using full setBounds rect to avoid DPI drift on Windows multi-monitor setups

Changes

src/renderer/src/pages/CommandBarPage.tsx

• Full rewrite: phonebook search via NethVoiceAPI.Phonebook.search() with 250ms debounce and stale-request cancellation
• Local operator filtering matching SearchNumberBox.getFoundedOperators() logic
• Avatar component with presence dot for operator results
• Keyboard navigation (ArrowUp/Down, Enter, Escape)
• useMemo for operator matching and result merging (avoids recomputation on hover/selection changes)
• RegExp created once before filter loop instead of per-operator
• Operators/avatars cached with 30s TTL and race-condition guard
• Proper IPC listener cleanup (removeAllListeners) on effect re-run
• Non-mutating mapContact (returns new object via spread)

src/main/classes/controllers/CommandBarController.ts

• New resize() method with full {x, y, width, height} rect in setBounds
• show() uses single setBounds call with full rect
• hide() calls window.hide() directly (no degenerate setBounds(0,0))

src/main/lib/ipcEvents.ts

• New handler for COMMAND_BAR_RESIZE IPC event

src/shared/constants.ts

• New COMMAND_BAR_RESIZE entry in IPC_EVENTS enum

Translations

• Updated placeholder in EN/IT: "Search contact or dial number..."
