Unify search UI pattern across Guides, Pack Templates, and Trips screens

[Copilot]

Guides, Pack Templates, and Trips screens used an older or incomplete search pattern. Updated all three to match the inline search pattern used in Packs and Catalog screens.

Changes

GuidesListScreen

• Wrap search results in LargeTitleHeaderSearchContentContainer within searchBar.content
• Add renderSearchContent() with result count, loading states, and empty states
• Hide category filters during active search
• Set iosHideWhenScrolling: false to persist search bar

PackTemplateListScreen

• Wrap search results in LargeTitleHeaderSearchContentContainer within searchBar.content
• Add renderSearchContent() with result count and empty states
• Hide featured packs section during active search
• Set iosHideWhenScrolling: false to persist search bar

TripsListScreen

• Wrap search results in LargeTitleHeaderSearchContentContainer within searchBar.content
• Add renderSearchContent() with result count and empty states
• Display TripCard components for each matching trip in search results
• Set iosHideWhenScrolling: false to persist search bar

Translation keys

• Added guides: searchGuides, result, results
• Added packTemplates: searchPlaceholder, searchTemplates, tryDifferentSearch, result, results
• Added trips: searchPlaceholder, result, results

Pattern

<LargeTitleHeader
  searchBar={{
    iosHideWhenScrolling: false,
    onChangeText: handleSearch,
    content: (
      <LargeTitleHeaderSearchContentContainer>
        {isSearching ? <SearchResults /> : <Placeholder />}
      </LargeTitleHeaderSearchContentContainer>
    ),
  }}
/>

Trip location search unchanged - it's a map-based location picker, not a list search screen.

@copilot TripListScreen

Updated TripListScreen to follow the same improved search pattern as Guides and Pack Templates screens (commit e6dcad7).

Changes:

• Added renderSearchContent() that shows search results inline within the search bar
• Displays result count when searching (e.g., "3 results")
• Shows empty state with icon and message when no results found
• Added iosHideWhenScrolling: false for better UX
• Added searchPlaceholder prop
• Added translation keys: trips.searchPlaceholder, trips.result, trips.results

The search now displays results within the search bar overlay, matching the pattern across all list screens in the app.

Fixed in commit 36e6d90.

The issue was that packId in TripForm could be null (from the form schema), but the Trip and TripInput types expect string | undefined. Added normalization to convert null to undefined before calling updateTrip or createTrip.
