Build TON transaction confirmation workflow

[konard]

Summary

• Add a shared TON transaction confirmation workflow with review state for amount, recipient, network fee, provider, total, limits, and risk indicators.
• Require platform biometric or password approval hooks before callers continue toward signing.
• Record pending, approved, rejected, and failed transaction history states for audit views.
• Document the new confirmation boundary in README and architecture docs.

Fixes #17

Reproduction and Verification

• Added test/ton-transaction-confirmation.test.mjs to cover transaction review fields, risk/limit indicators, approval requirements, history status recording, and validation before approval bridge calls.

Tests

• node --test test/ton-transaction-confirmation.test.mjs
• npm test
• npm run validate:foundation
• npm run validate:release

Screenshots

Not applicable: this PR adds the shared confirmation workflow boundary and tests, not a rendered UI shell.
