Offline-First PWA with a Persistent Transaction Queue

[meshackyaro]

Description

This issue aims to address the implementation of Offline-First PWA with a Persistent Transaction Queue.

The core objective is to: Turn the dashboard into an installable PWA that queues user actions while offline, persists them durably, and replays/re-signs them against the current ledger sequence on reconnect.

By completing this feature, we will ensure that the TrustFlow protocol maintains its high standards for security, usability, and decentralized logic. This issue requires careful attention to the Frontend architecture and adherence to the existing project conventions.

When picking up this issue, please ensure you document any new dependencies or architectural decisions made during development.
