- Remove pin/unpin and auto-hide hover mechanism (isPinned, isHovering,
hoverTimeout, showSidebar/hideSidebar, updateAutoHideState, etc.)
- Remove global show_folder_sidebar setting (SettingsManager,
PageControls, recipes, backend default)
- Simplify sidebar visibility to a single per-page toggle:
· Dedicated chevron-left button in header to hide sidebar
· Edge indicator (chevron-right) to restore when hidden
· No dropdown, no hover area, no pin button
- Add _migrateOldSettings() to convert old sidebarPinned and
show_folder_sidebar states to per-page sidebarDisabled
- Fix sidebar flicker on page load: CSS defaults to off-screen,
JS explicitly sets .visible or .hidden-by-setting
- Remove obsolete CSS classes: auto-hide, hover-active, collapsed
- Remove i18n keys: pinSidebar, unpinSidebar, moreOptions
- Update test mocks for the new initialize() interface
- Add getMappableBaseModelsDynamic to constants.js mocks in test files
- Remove refs/enums.json temporary file from repository
Fixes test failures introduced in previous commit.
