fix(bedrock): validate TagResource ARN, add embed schema, fix profanity and deployments

[vieiralucas]

Summary

• Reject empty/missing resourceARN in TagResource with ValidationException instead of storing tags under empty key
• Return embedding vector schema for amazon.titan-embed-* models instead of text-generation schema
• Use word-boundary matching for profanity detection to prevent false positives (e.g., "assignment" no longer matches "ass")
• Serialize non-string hyperparameter values instead of silently converting to empty string
• Generate unique deployment names when modelDeploymentName is not provided

Addresses unresolved Cubic findings from PRs #260, #266.

Test plan

• cargo clippy -p fakecloud-bedrock -- -D warnings passes
• All unit tests pass

Summary by cubic

Fixes correctness and robustness in fakecloud-bedrock: validates TagResource ARN, returns proper Titan embed schema across variants, improves profanity checks, and hardens deployment/hyperparameter handling. Addresses remaining Cubic findings from earlier PRs.

• Bug Fixes
  • Validate TagResource resourceARN; return ValidationException when missing or empty.
  • Return embedding vector schema for amazon.titan-embed* models (prefix match) instead of text-generation.
  • Use word-boundary matching for profanity to avoid false positives (e.g., "assignment").
  • Serialize non-string hyperparameter values; auto-generate unique deployment names when modelDeploymentName is not provided.

^{Written for commit 6ef8765. Summary will update on new commits.}
