fix: localize settings labels, correct THB/TWD names, and fit receive QR on short windows

[o-mid]

Summary

• Fix swapped THB / TWD fiat names (Thai Baht vs New Taiwan Dollar) and the Thaiwan typo.
• Show localized strings for fee priority, fiat/swap API mode, theme mode, and sync-status display. Settings rows were using hardcoded English .title values even though toString() / ARB keys already existed.
• Cap the receive QR size against window height so the code is not clipped on short Linux desktop windows.

Test plan

• Settings → Display → currency list: THB is Thai Baht with Thailand flag; TWD is New Taiwan Dollar with Taiwan flag
• Switch app language to Italian
• Settings → Other → fee priority shows Automatica/Lento/Media/Veloce (or the existing Italian ARB values), not English Slow/Medium/Fast
• Settings → Connections → Fiat API / Swap summary shows Abilitato / Solo Tor / Disabilitato
• Settings → Display → appearance chips show device/light/dark translations, not System/Light/Dark
• Settings → Display → sync status options use the existing ETA / remaining-blocks strings
• Receive screen on a short landscape window (Linux or resized desktop): full QR visible and scannable; address remains copyable/shareable
