feat: Add Kurdistan sun animation for swap processing

Added animated Kurdistan-themed loading indicator that displays during swap transactions:
- KurdistanSun component with 21 rays (Kurdistan flag symbolism)
- White center sun with glow effects
- Rotating colored halos: green (outer), red (middle), yellow (inner)
- Full-screen overlay with backdrop blur during processing
- Fixed timing: dialog closes before animation shows
