- Change RefererId, Balance, GiftAmount, Commission from int64 to *int64 in UpdateUserBasiceInfoRequest
- When field is nil (not sent by client), skip update entirely — prevents zero-value from clobbering existing data
- When field is non-nil, dereference and apply as before (including explicit 0 to clear a value)
- Mirrors the existing guard pattern already used for Avatar, ReferCode, Enable, IsAdmin, etc.
Fixes: RefererId unconditional overwrite at line 123 (P02)
Fixes: Balance/GiftAmount/Commission triggering adjustment to 0 when omitted (P03)
