refactor: read signature flow from file data in frontend

Replace global config usage with file-level signature flow from store.

- RequestSignatureTab.vue: Compute signatureFlow from file data
- Signer.vue: Read signatureFlow from file instead of loadState
- Signers.vue: Check file.signatureFlow for ordered flow mode
- files.js: Use file.signatureFlow for signer order management

This enables per-file signature flow configuration in the UI.
