fix: enable link search in feature image caption and center caption text

[Dikshant0Git]

Context
#28359

Problem

The feature image caption editor in Ghost Admin runs as an isolated instance separate from the main editor canvas. This isolation introduced two specific UI/UX issues:

• Missing Search Dropdown: The component did not pass down the global configuration context. Because cardConfig.searchLinks was missing, the editor was forced to drop back to a basic text input fallback that lacked autocomplete capabilities and collapsed heavily under short character selections.
• Layout Mismatch: The feature image caption was left-aligned by default, breaking visual consistency with standard body-level image card captions which are center-aligned.

Fix

• ghost/admin/app/components/koenig-lexical-editor-input.js: Injects Ember's search, settings, and store services directly into the component. It implements a robust, cached, and filtered asynchronous searchLinks method within the React wrapper and threads it directly into the caption editor as a structured cardConfig prop. This restores the full autocomplete suggestion list when users format links.
• ghost/admin/app/styles/layouts/editor.css: Adds a clean CSS rule targeting .gh-editor-feature-image-caption specifying text-align: center to ensure uniform layout alignment.
• No Parent Bloat: The layout configuration and logic are entirely contained within the specific component that initializes the feature image caption composer, avoiding the need to alter high-level handlebars templates or pollute parent prop chains.

Tests

Added local unit and static validation tests covering the new behavior (test_search_links.js):

• Verified correct default posts resolution and caching logic when the search term is empty.
• Verified proper handling of task cancellations and error propagation within the searchLinks context layer.

Scope

The underlying layout collapse symptom—where the fallback input box shrinks tightly around a small text range when a configuration is absent—is caused by the basic input field layout inside the engine package and is handled directly in the Koenig repository workspace.

This PR fixes the root problem inside Ghost Admin by ensuring the correct configuration context is always provided to the composer.

However, the visual symptom of that bug—where the fallback input box shrank so tightly around small text selections that it became unusable—lives inside the core editor package. To address this comprehensively, a companion PR has been submitted to the Koenig repository:

• Ghost PR (This one): Restores the missing cardConfig context so the advanced link autocomplete toolbar works seamlessly.
• Koenig PR (Cross-referenced): Adds a defensive min-w-[240px] rule to LinkInput.jsx to ensure that even if a fallback input is triggered anywhere else in the ecosystem, the UI remains resilient and usable.

By decoupling these fixes, we ensure immediate feature availability in Ghost Admin while contributing a permanent UI safety layer to the shared Koenig codebase.

Walkthrough

KoenigLexicalEditorInput is extended with three injected Ember services (search, settings, store) and a defaultLinks cache. An async searchLinks(term) function is added: when called without a term it fetches the latest 5 published posts via store.query, decorates them with decoratePostSearchResult, and caches the result; when a term is supplied it calls search.searchTask.perform, suppresses task cancellation errors via didCancel, filters results to published Posts/Pages, removes /404/ Staff URLs, and decorates the matching items. The function is bundled into cardConfig and passed as a prop to KoenigComposer. Separately, the editor CSS adds appearance: none to the feature image caption/alt-text rule and introduces a dedicated text-align: center rule for .gh-editor-feature-image-caption.

@service session is injected but never used in this component. The other injected services (search, settings, store) are all used in searchLinks, but session has no references.

using didCancel(error), the function currently returns undefined when a
cancellation error occurs. Change the bare return statement to return an empty
array instead, so that the function consistently returns an array type
regardless of whether it completes successfully or is cancelled.
