Migrate generic `new_interaction` event to dedicated events

[ValentinTrinque]

Today, we emit a generic new_interaction event with the specific interaction event as a value.

After a discussion with @notbot00, we came to the conclusion having specific events is much easier for the frontend.

Technical implications

On the backend

- wailsRuntime.EmitEvent(ctx, "new_interaction", interaction)
+ wailsRuntime.EmitEvent(ctx, interaction.Name, interaction)

On the frontend

- runtime.OnEvent("new_interaction", func() {
-   // handling generic event
- })
+ runtime.OnEvent("request_wallet_connection", func() {})
+ runtime.OnEvent("request_transaction_review_for_sending", func() {})
+ // Etc...

Events to listen to

• "ERROR_OCCURRED"
• "INTERACTION_SESSION_BEGAN"
• "INTERACTION_SESSION_ENDED"
• "LOG"
• "REQUEST_PASSPHRASE"
• "REQUEST_PERMISSIONS_REVIEW"
• "REQUEST_SUCCEEDED"
• "REQUEST_TRANSACTION_REVIEW_FOR_SENDING"
• "REQUEST_TRANSACTION_REVIEW_FOR_SIGNING"
• "REQUEST_TRANSACTION_REVIEW_FOR_CHECKING"
• "REQUEST_WALLET_CONNECTION_REVIEW"
• "REQUEST_WALLET_SELECTION"
• "TRANSACTION_FAILED"
• "TRANSACTION_SUCCEEDED"
