fix(network): switching from testnet to mainnet does not re-trigger indexing

[zintarh]

Summary

When a user switches network using the NetworkToggle during or after loading, the indexer continues to display data for the previous network.

Steps to Reproduce

1. Start a wrap on Testnet
2. Halfway through loading, switch to Mainnet
3. Observe stale testnet data displayed

Acceptance Criteria

• Network switch resets wrap store and restarts indexing
• User sees a confirmation prompt before the network switch if data is already loaded
• Contract address re-loads for the new network per config/contracts.ts

Scope: store
Type: fix
Difficulty: Medium

GM Maintainer,
I'd like to work on this issue. I will ensure that switching networks properly resets the wrap store and restarts indexing so stale data is not retained. I will also add a confirmation prompt when a network switch is attempted while data is already loaded, and ensure contract addresses are reloaded correctly from config/contracts.ts for the selected network.
Please assign this issue to me.
