Add audit trail for admin actions emitted as contract events

[greatest0fallt1me]

Description

This is a smart-contract issue. Admin actions (set_paused, set_admin, set_token_allowed) do not emit events. Add typed events for each so off-chain auditors can rebuild the timeline.

Requirements and Context

• Three new event types
• Topics include admin address
• Tests assert payloads
• Must be secure, tested, and documented
• Should be efficient and easy to review

Suggested Execution

1. Fork the repo and create a branch

   git checkout -b feat/admin-audit-events

2. Implement changes
   • contracts/contracts/streampay-stream/src/events.rs
   • contracts/contracts/streampay-stream/src/lib.rs
3. Test and commit
   • cargo test -p streampay-stream admin
   • Include test output and notes in the PR

Example commit message

feat: audit events for admin actions

Acceptance Criteria

• Events emitted
• Tests assert
• Docs updated

Guidelines

• Topic ordering stable
• Clear documentation and inline comments
• Timeframe: 96 hours

I would like to contribute to Issue #458: Add Audit Trail for Admin Actions Emitted as Contract Events.

I have experience working with Soroban smart contracts and writing tests for contract events. I'd be happy to implement typed audit events for admin actions and ensure they are emitted consistently for off-chain auditing.

My plan is to:

• Add typed events for set_paused, set_admin, and set_token_allowed
• Include the admin address in the event topics with stable topic ordering
• Add tests that verify the emitted event topics and payloads
• Update the documentation and inline comments to reflect the new event behavior
• Ensure the implementation is secure, well-tested, and passes the relevant test suite

I would appreciate being assigned this issue. Thank you for your consideration.
