feat: rename blockchain connector type to application

[jvallesm]

Because

• feat(vdp): add component definition list endpoint protobufs#274 removed the Blockchain
  connector type and modified the connector and operator list view type.
• Once chore: rename blockchain type to application connector#131 is merged, numbers connector will become an application connector.

This commit

• Updates the auto-generated proto Go code, adapting the backend to the changes:
  • Modifies the Blockchain enum value in the database via a migration.
  • Modifies type conversions to take Application connector into account.
  • Removes deprecated lookup methods.
  • Updates VIEW_XXX enum values.

✅ QA

• On main, I created a Numbers connector and a pipeline using it
• I switched to jvalles/ins-3739-rename-blockhain-type-to-application in pipeline-backend, connector and console.
• The pipeline kept working ✅
• A new pipeline with a new connector worked as well ✅

Additionally, I tested the API endpoint:
