Gift patch fixes.
- Fake transfer now works end to end: rewrites the
STARGIFT_NOT_UNIQUE
payment-form error and clears the transfer cooldown ("Try Later — transfer in
N days"), so the spoofed transfer actually goes through. - Spoof profile unique gifts: the model and symbol (pattern) now render —
their emoji are auto-loaded by id at startup, so you no longer have to open the
packs by hand. - Auto-load also covers Spoof profile gifts and Show hidden gifts, so their
custom emoji load automatically too.
