Implement-Decentralized-Payout-Trigger

[Securify001]

Summary

Changes Made

1. Added CurrentCycleContributions Storage Key
   Added new DataKey::CurrentCycleContributions variant to track contributions per cycle efficiently without iterating over all members.
2. State Management Optimization
   contribute(): Now initializes CurrentCycleContributions to 0 when a new cycle starts, and increments it by 1 on each contribution.
   reset_cycle(): Now resets CurrentCycleContributions to 0 when a cycle is reset.
3. Implemented trigger_payout() Function
   Signature: pub fn trigger_payout(env: Env, caller: Address, recipient: Address)
   Access Control: Caller must be a member (requires authentication)
   Pool Fullness Check: Pool is considered full when CurrentCycleContributions == CycleMemberCount
   Recipient Validation: Recipient must be a member and must not have received a payout this cycle
   Payout Execution: Same logic as admin payout() function
   Event: Emits trg_pay event on successful payout
4. Unit Tests Added
   ✅ test_trigger_payout_success: Member triggers payout when pool is full (succeeds)
   ✅ test_trigger_payout_pool_not_full: Member triggers payout when pool is NOT full (panics with "Pool is not full")
   ✅ test_trigger_payout_non_member: Non-member attempts to trigger payout (panics with "Caller is not a member")

Files Modified

lib.rs - Added CurrentCycleContributions storage key, modified contribute() and reset_cycle(), added trigger_payout() function
test.rs - Added 3 unit tests for trigger_payout

All acceptance criteria have been met:

✅ Reduce Admin Reliance - Members can now trigger payouts
