This pull request introduces stricter validation for organization and resource identifiers to improve security and consistency across API endpoints. The main changes add UUID format checks for organization IDs in license-related routes and type guard functions for resource and identity provider IDs in server-side actions, with corresponding input validation in proxy functions.

Validation improvements for organization IDs:

• Added UUID v4 format validation for orgId in generateNewLicense.ts, ensuring only valid organization IDs are accepted when generating new licenses. [1] [2]
• Updated listGeneratedLicenses.ts to require orgId to match a UUID v4 pattern, rejecting invalid or missing organization IDs with a clear error message.

Security enhancements in server-side actions:

• Introduced isValidResourceId and isValidIdpId type guard functions in server.ts to validate resource and identity provider IDs, restricting accepted formats.
• Added input validation using these type guards in proxy functions (resourcePasswordProxy, resourcePincodeProxy, resourceWhitelistProxy, resourceAccessProxy, validateOidcUrlCallbackProxy, generateOidcUrlProxy), throwing errors for invalid IDs to prevent unsafe requests. [1] [2] [3] [4] [5] [6]
• Enforced alphanumeric, dash, and underscore restrictions for orgId in generateOidcUrlProxy to further strengthen input validation.
