v0.3.0 — Stats, URLs & Domains

Flicker moves out of beta. It's stable enough for daily use, but still
early access expect new features and occasional rough edges while the
app and its Emberly integration keep growing.

Added

• Stats page: replaces the old "Coming Soon" placeholder with real usage
  data pulled from your Emberly account — total files, storage used, short
  URL count and clicks, total views/downloads, domain count, a 14-day
  uploads chart, and a recent-uploads list (sections respect your plan's
  actual limits instead of showing data you don't have access to).
• URL Shortener: a new page to turn a long link into a short one and copy
  it, without leaving the app.
• Custom upload domain: Settings → Capture now has a domain picker sourced
  from your verified Emberly domains, and it's respected by every upload
  path (drag-and-drop, clipboard, hotkey/screenshot capture).
• File management from Upload History: opening a history item now lets you
  toggle its visibility (Public/Private) and set a password directly,
  without needing the website. Deleting a history item now also deletes the
  file from your Emberly account, not just the local list entry.
• Perks display: Settings → Account now shows your active perk bonuses
  (extra storage, extra domains) when you have any active.

Fixed

• get_profile, validate_token, and get_stats called API endpoints that
  don't exist on the real server (leftover scaffolding with no working UI
  behind it) and always failed. They now call the correct endpoints
  (/api/profile, /api/analytics/summary) and return real data.
• delete_file existed in the Rust API client but was never wired to a
  Tauri command, making it unreachable from the UI. It's now registered and
  used by Upload History's delete action.
