chore: reload app on service change

[Bushstar]

• Resolves: Extension: better error handling if no keymaster service available #945
• Refresh app when service URLs change
• Allow UI to load even when keymaster is not contactable

[Copilot]

Pull request overview

This PR enables the wallet application to reload when service URLs are changed, and allows the UI to load even when the keymaster service is not contactable. The changes improve resilience by wrapping service calls in separate try-catch blocks and exposing the initialiseServices function to allow manual reinitialization.

Key changes:

• Exposed initialiseServices function in wallet context interfaces for both React wallet and Chrome extension
• Modified service initialization error handling to prevent blocking UI load on keymaster failures
• Added service reinitialization capability to settings tabs with user feedback
