This will get rid of the frontend validations we have by default for the inputs with type EMAIL_INPUT.
Can't we keep this as a fallback validation for EMAIL_INPUT type inputs when the flow validation rules are not defined?
I prefer not to remove this rule at this point as we still haven't fully incorporated flow validation rules to the thunderid console.
@brionmario WDYT?

Lets keep the default validation.
@coderabbitai Create an issue in https://github.com/thunder-id/thunderid to centralize and maintain a default set of validations in the @thunderid/browser or @thunderid/javascript that can be reused.

## Summary
Centralize the SDK default client-side validation rules in a reusable API from `@thunderid/browser` or `@thunderid/javascript`.
## Rationale
The React authentication forms must retain default validation for inputs such as `EMAIL_INPUT` while ThunderID Console flow validation rules are not yet fully available. The current validation logic is duplicated in UI components. Centralizing the rules will provide consistent behavior across SDKs and avoid hardcoded validation logic in individual flows.
## Affected areas
- `@thunderid/browser`
- `@thunderid/javascript`
- `@thunderid/react` authentication flows, including sign-in, sign-up, and recovery
- Flow component types such as `EMAIL_INPUT`
## Required changes
1. Define and export a maintained default-validation API from `@thunderid/browser` or `@thunderid/javascript`.
2. Include an email-format fallback for `EMAIL_INPUT` when the flow component has no applicable declarative validation rule.
3. Define precedence between declarative flow rules and default validation rules.
4. Update React authentication forms to consume the shared API instead of defining email validation inline.
5. Ensure validation messages use the existing translation mechanism and do not expose raw translation keys.
## Acceptance criteria
- A consumer can apply the shared default validation based on an embedded flow component type.
- `EMAIL_INPUT` has client-side email-format validation when no applicable flow validation rule is present.
- Declarative flow validation behavior remains supported and has documented precedence over fallback validation.
- Sign-in, sign-up, and recovery use the shared validation API.
- Validation errors are translated through the SDK translation function.
- Unit tests cover valid and invalid email values, absent flow rules, and declarative-rule precedence.

Learning: ThunderID Console has not yet fully incorporated flow validation rules. React authentication forms must retain default client-side validation, including `EMAIL_INPUT` fallback validation, until declarative flow rules are available.

For now, shall we have this if condition check for EMAIL_TYPE after the ruleValidator check? @brionmario @ThaminduDilshan . That way the check will still exist for EMAIL_TYPE and for the cases where flow validation rule is incorporated, that check will happen first and proper validation message will be rendered.

Purpose
Fixes two bugs in the
@thunderid/reactSDK:Validation error messages were frozen in the language active at validation time. Switching the UI language updated all other strings but left displayed errors untranslated.
Invalid email input showed the raw i18n key
field.email.invalidinstead of a translated error message, across all three identity deployments.Approach
1. — Error re-translation on language switch
The root cause:
useFormstores errors as resolved translated strings in state. When the language changes, new validators are built correctly but nothing re-runs them on already-displayed errors.Fix:
revalidateTouchedFields()touseForm— a stable callback (empty deps) that uses "latest value" refs to re-run validation on all touched, client-validated fields inside a functionalsetFormErrorsupdater. Fields whose errors originated from the server (no matchingFormFieldconfig) are skipped to prevent server messages from being silently wiped.BaseSignIn, added auseEffect([currentLanguage, revalidateTouchedFields])to call it on every language change.2. — Raw i18n key rendered as email error
t('field.email.invalid')— a key that never existed in any translation bundle. This check fired before the declarativeruleValidator(which correctly uses the translatedvalidation.email.formatkey from the flow YAML), short-circuiting it entirely.BaseSignIn,BaseSignUp, andBaseRecovery. Email validation now flows exclusively through the declarative rule system with properly translated messages.Related Issues
