Pull request overview
Consolidates per-page hCaptcha handling into a single ICaptchaValidationService that returns explicit outcomes (Disabled / MissingToken / Unavailable / Invalid / Valid), and updates chat plus the Identity pages (Login, Register, ForgotPassword, ResetPassword, ResendEmailConfirmation) to use it. Register retains its detailed hCaptcha error-code mapping; other callers use a generic message. Adds TUnit tests for the new service.
Changes:
- New shared service
CaptchaValidationService, result record, and outcome enum centralizing captcha policy. - Identity pages and
ChatControllermigrated off directICaptchaServiceusage to the shared validation layer. - Added
CaptchaValidationServiceTestscovering disabled, missing token, unavailable, invalid, and valid paths.
