build(deps): bump react-hook-form from 7.86.0 to 7.87.0 in /frontend

[dependabot]

Bumps react-hook-form from 7.86.0 to 7.87.0.

Release notes

Sourced from react-hook-form's releases.

Version 7.87.0

✨ Features

• Add shouldTouch option to trigger() ([#13671](react-hook-form/react-hook-form#13671))

  setValue already supported shouldTouch; trigger() now does too. This allows you to mark field(s) as touched after manual or programmatic validation, such as validate-on-mount or multi-step form navigation, without needing a setValue workaround:

  // Mark a single field as touched after validating it
  await trigger('firstName', { shouldTouch: true });
  // Mark every mounted field as touched after validating the whole form
  await trigger(undefined, { shouldTouch: true });

• Add OpaqueTypes registry for opaque leaf types ([#13676](react-hook-form/react-hook-form#13676))

  Recursive type helpers (Path, DeepPartial, DeepRequired, FieldErrorsImpl, etc.) previously stopped only at Primitive | BrowserNativeObject. As a result, rich third-party value types such as Dayjs and Decimal could be recursively traversed member-by-member, potentially causing TypeScript to report "Excessive complexity" diagnostics on large form types.

  You can now register a type as an opaque leaf via declaration merging:

  import type { Dayjs } from 'dayjs';
  declare module 'react-hook-form' {
  interface OpaqueTypes {
  dayjs: Dayjs;
  }
  }

  While the registry is empty, types remain identical to the existing behavior. This is purely opt-in.

🐞 Fixes

• Fix inconsistent behavior among useController().field.onChange()-like APIs. ([#13673](react-hook-form/react-hook-form#13673))
• Fix Controller under a null parent submitting undefined instead of a value. ([#13675](react-hook-form/react-hook-form#13675))
• Fix ERR_MODULE_NOT_FOUND when resolving react-hook-form due to a react-server declaration in Next.js builds. ([#13682](react-hook-form/react-hook-form#13682))
• Fix useWatch never reconciling when an Activity subtree is hidden on its first render. ([#13683](react-hook-form/react-hook-form#13683))
• Fix resetField not recomputing isValid for subscribe-only consumers. ([#13684](react-hook-form/react-hook-form#13684))
• Fix generateWatchOutput ignoring defaultValue for an array of names. ([#13686](react-hook-form/react-hook-form#13686))
• Fix useFormState never reconciling when an Activity subtree is hidden on its first render. ([#13687](react-hook-form/react-hook-form#13687))
