export public lambda arns to avoid CDK deadly embrace lock in beta deployment

[landonshumway-ia]

We have removed the public API search endpoints from beta (see #1591). The deployment for that change failed due to the 'deadly embrace' issue in CDK where a stack attempts to remove an unneeded export, but CloudFormation can't allow that deletion until the consuming stack of that export has been updated. This adds dummy exports for those lambdas to fix the deployment and allow all the stacks to be updated.

📝 Walkthrough

Walkthrough

CloudFormation exports for public lookup Lambda ARNs are consolidated from the PublicLookupApiLambdas initializer to parent stacks (ApiLambdaStack and SearchPersistentStack) across compact-connect and cosmetology-app. Dummy exports are removed and replaced with explicit retention exports to prevent "deadly embrace" deployment failures when beta API routes are disabled.

Changes

Cross-Stack CloudFormation Export Consolidation

Layer / File(s)	Summary
PublicLookupApiLambdas documentation and dummy export removal backend/cosmetology-app/stacks/api_lambda_stack/public_lookup_api.py	Documentation clarifies that the query providers endpoint uses SearchPersistentStack.public_handler and is no longer wired to the API. The previous CDK "dummy export" for query_providers_handler.function_arn is removed after being superseded by explicit exports in parent stacks.
Cosmetology-app export consolidation backend/cosmetology-app/stacks/api_lambda_stack/__init__.py, backend/cosmetology-app/stacks/search_persistent_stack/__init__.py	Explicit export_value(...) calls are added to ApiLambdaStack for public_lookup_lambdas handlers and to SearchPersistentStack for the public search handler to preserve CloudFormation cross-stack imports and prevent export deletion failures during beta deployments.
Compact-connect ApiLambdaStack export consolidation backend/compact-connect/stacks/api_lambda_stack/__init__.py	Explicit exports are added for the two public lookup Lambda ARNs to preserve CloudFormation exports in the beta environment where those API routes are not deployed.

Poem

🐰 A rabbit hops through stacks so tall,
Exports dance free to heed the call,
No deadly embrace shall block the way,
When beta routes must take a break today!
Cross-stack harmony, peaceful and bright, ✨

SearchPersistentStack.public_handler to point at
SearchPersistentStack.search_handler.public_handler (i.e., the lambda is exposed
as search_handler.public_handler), so the future cleanup targets the correct
