[Good First Issue] Add tooltip to preset buttons showing exact dimensions

[magic-peach]

Overview

Preset buttons in PresetSelector.tsx show the name (e.g., 'Reels') but not the exact dimensions. Adding a tooltip with dimensions helps users make informed choices.

Task

Update preset buttons to show dimensions on hover:

<button title="1080 × 1920 — 9:16 vertical"...>
  Reels
</button>

Acceptance Criteria

• Each preset button has a title attribute with exact dimensions
• Format: '{width} × {height} — {ratio} {orientation}'

Good first issue — estimated effort: 20 minutes
