feat(input): localize format & selection submenu labels

[eszlamczyk]

What/Why?

Extends PR #415 localizable-labels pattern from EnrichedMarkdownText to the input context menu introduced in PR #409. Apps that localize the renderer's selectionMenuConfig would otherwise still see an English "Format / Bold / Italic / … / Copy as Markdown" submenu on EnrichedMarkdownTextInput - this closes that gap.

Nine new label slots, all opt-in and additive to existing config:

• formatMenuConfig.{bold,italic,underline,strikethrough,spoiler,link} - each now takes { enabled?, label? } instead of boolean.
• inputSelectionMenuConfig.format and .copyAsMarkdown - same shape; format.label controls the submenu title itself.

The legacy boolean form keeps working at runtime and logs a one-time warnOnce deprecation; removed in 0.8. Same shape evolution as PR #415.
JS resolves the English defaults so native code carries no fallback strings - Android / iOS / macOS just read labels straight from the config struct or data class, matching the convention from #415.

Refactor: normalizeMenuItem + warnOnce extracted from src/native/EnrichedMarkdownText.tsx into src/shared/normalizeMenuItem.ts so both selectionMenuConfig (text) and formatMenuConfig / inputSelectionMenuConfig (input) share deprecation rules and fallback semantics.

Not in scope (intentional):

• System Cut / Copy / Paste / Select All in the input — UIKit (UITextView) and Android's ActionMode add these and they're already localised by the device language. No prop needed.
• Link prompt dialog strings ("Add Link", "Edit Link", "Update", "Add", "Cancel", URL placeholder) - separate UI surface; would expand the i18n API to dialog text. Worth a follow-up/discussion with the team if needed.
• iOS image long-press sheet ("Save to Camera Roll", "Copy", …) - UIKit owns this for NSTextAttachment images; would require attaching UIContextMenuInteraction to image regions. TODO already noted in ios/utils/EditMenuUtils.h.

Platforms: iOS, Android, macOS

Testing

apps/react-native-example/.rnstorybook/stories/components/EnrichedMarkdownTextInput/props/FormatMenu.stories.tsx extended with three stories mirroring the SelectionMenu story layout:

1. Default - Italian labels for all 9 slots; every label + enabled toggle exposed as controls so you can dial them live.
2. EnglishDefaults - no formatMenuConfig / inputSelectionMenuConfig; verifies the JS-side fallback path resolves to the built-in English labels across all three platforms.
3. DeprecatedBooleanForm - passes legacy bold: false / copyAsMarkdown: false; verifies the warnOnce deprecation fires once and visibility still toggles correctly through the compat shim.

Pull request overview

This PR extends the localized-labels pattern used by EnrichedMarkdownText to the EnrichedMarkdownTextInput selection context menu, so the “Format” submenu and its items (plus “Copy as Markdown”) can be localized via JS-provided labels while keeping native code free of fallback strings.

Changes:

• Introduces a shared normalizeMenuItem helper (plus warnOnce) to normalize { enabled, label } items and support legacy boolean configs with a one-time deprecation warning.
• Expands input context-menu config plumbing to carry submenu/action/item labels through codegen → iOS/Android menu construction.
• Updates the example Storybook stories to demonstrate defaults, localized labels, and the deprecated boolean runtime shim.
