Harden escrow lifecycle and dispute settlement semantics

[grantfox-oss]

Make escrow creation, release, cancellation, and dispute resolution safer by enforcing consistent lifecycle state transitions and explicit safety checks.

• Affected files: app/contract/contracts/Folder/src/escrow.rs, app/contract/contracts/Folder/src/dispute.rs, app/contract/contracts/Folder/src/escrow_id.rs, app/contract/contracts/Folder/src/escrow_id_test.rs, app/contract/contracts/Folder/src/lib.rs, app/contract/contracts/Folder/src/storage.rs, app/contract/contracts/Folder/src/admin.rs, app/contract/contracts/Folder/src/test.rs
• Acceptance criteria:
  • Escrow state transitions are invalid if they break lifecycle assumptions or attempt duplicate settlement.
  • Dispute and release flows maintain deterministic result ordering and cannot leave funds in ambiguous states.
  • Test coverage exercises dispute resolution, release, cancellation, and partially settled edge cases.
