fix: strip unresolved placeholders on deploy instead of throwing

[ankita10119]

🔧 Changes

Previously, deploying a resource with an unresolved ##...## or @@...@@ placeholder would throw an error and abort the deploy. This caused the export→import round-trip to fail for connections and other resources where the CLI auto-generates secret placeholders on export (e.g. ##CONNECTIONS_WAAD_SECRET##), since Auth0 does not expose the actual secret value, making it impossible for users to provide the keyword mapping.

Change: Instead of throwing, unresolved placeholders are now stripped from the payload before the API call, with a warn log per field. Auth0 preserves its existing value for any stripped field.

• Added stripUnresolvedPlaceholders utility in src/tools/utils.ts
• APIHandler.processChanges (create, update, conflict paths) now calls stripUnresolvedPlaceholders in place of validateNoUnresolvedPlaceholders

🔬 Testing

• Unit tests updated in test/tools/utils.test.js and test/tools/auth0/handlers/default.tests.ts
• Tested against real tenant: exported a WAAD connection (producing ##CONNECTIONS_WAAD_SECRET##), ran import without defining the mapping, field was stripped with a warning and the connection updated successfully

I think the suggested key here might be slightly off. It's derived from the field name rather than the placeholder itself. For options.client_secret: ##CONNECTIONS_WAAD_SECRET##, it would tell the user to define CLIENT_SECRET, but the value they actually need to map is CONNECTIONS_WAAD_SECRET, so following the message as-is wouldn't quite work. Could we maybe pull the name from value instead (stripping the ##/@@)?

It's already available right there in the loop, so it might be a small change.
