Fix frame size not persisting across restarts

[elvistranhere]

Summary

• The "Full width" toggle in settings was saved to localStorage correctly when toggled, but on app launch it was unconditionally overwritten to false before the store initialized
• One-line fix: remove the expandedUI: false override in theme.ts so the saved preference is respected on restart

What changed

src/renderer/theme.ts:

-// Always start in compact UI mode on launch.
-const saved = { ...loadSettings(), expandedUI: false }
+const saved = loadSettings()

Test plan

• Toggle "Full width" on in settings
• Restart the app
• Verify full width mode is still active
• Toggle "Full width" off, restart, verify it stays off
• Verify theme mode and sound settings still persist correctly (no regression)
• npm run build passes with zero errors

Fixes #30

Pull request overview

Fixes UI width preference persistence by ensuring the saved expandedUI setting from localStorage is no longer overwritten during theme store initialization, addressing issue #30.

Changes:

• Stop forcing expandedUI: false at startup so the stored “Full width” preference is respected after restart.
• Rely solely on loadSettings() for initial theme store values.
