fix: adding validation when adding link to message composer

[divyanshu-patil]

Proposed changes (including videos or screenshots)

• Added regex-based validation to ensure URLs start with http:// or https://.
• Disabled Add button until the URL is valid (UX improvement).
• Added i18n keys for the new validation message.
• Included translations for:

1. English
2. Spanish (es)
3. Portuguese (pt-BR)
4. Hindi (hi)

Issue(s)

closes #37572

Steps to test or reproduce

affected screens

Further comments

• Please review the new i18n keys for naming consistency.
• Let me know if additional languages should be included.
• If the regex or UX behaviour (disabling the button) needs refinement, I can update accordingly

Walkthrough

URL validation was added to the message composer link modal: the form now validates required http/https URLs on change, shows inline error messages, and disables confirm until valid. Translation keys for the validation messages were added in en, es, hi-IN, and pt-BR.

Changes

Cohort / File(s)	Summary
Link Composer Validation apps/meteor/app/ui-message/client/messageBox/AddLinkComposerActionModal.tsx	Switched useForm mode to onChange and read formState; wrapped URL input with Controller adding required and http/https pattern validation; render FieldError from fuselage; disable confirm button when form is invalid.
Localization Files packages/i18n/src/locales/en.i18n.json, packages/i18n/src/locales/es.i18n.json, packages/i18n/src/locales/hi-IN.i18n.json, packages/i18n/src/locales/pt-BR.i18n.json	Added translation keys URL_is_required and URL_must_start_with_'http://'_or_'https://' with locale-specific messages for URL validation.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Review focus:
  • AddLinkComposerActionModal.tsx — verify regex correctness, translation keys usage, and correct wiring of Controller + formState.
  • Localization files — ensure key names match usage and translations are accurate/consistent.

Poem

🐰 I nibbled on a tiny clue,

"http or https," I quietly knew.
No empty hops, no wild link play,
Errors guide — now all's OK.
A little rabbit guards the way. 🥕🔗
