feat: show starred endpoints on Home regardless of state

[nabramovitz]

What

Home previously double-filtered its cards to connected endpoints, so a starred endpoint that went down silently disappeared — absence read as "not favorited" rather than "down". Home can now answer both questions the issue names: "show me my connected endpoints" and "show me my starred endpoints, up or not".

Changes

Which-endpoints control

• New header segmented control: Favorites | Connected | All (replaces the "Show connected endpoints" checkbox row that lived inside the layout menu — a content filter fused into a presentation menu, with the active mode invisible until opened).
  • Favorites: every starred endpoint (directly, or via starred child entities), any connection state.
  • Connected: every connected endpoint, favorites first (previous behavior).
  • All: every registered endpoint, any state, favorites first.
• The persisted boolean preference migrates to the three-way mode; the deployment default (homeViewShowFavoritesOnly) keeps its meaning.

Disconnected presentation

• A shown endpoint that is disconnected renders a Disconnected panel with a Connect button (the endpoints-page connect dialog) — its home card never loads, so no half-loaded or error card. Connecting while the card is on screen swaps the real card in.
• Token expiry presents as Disconnected only when jetstream cannot mint a fresh session: /pp/v1/info now exposes token_expiry and token_renewable (refresh token present) per connected endpoint. Refresh-capable endpoints (UAA/SSO) renew transparently on use, so their hourly access-token expiry stays harmless — the rule exists for korifi-style pasted tokens (Support Korifi (Cloud Foundry on Kubernetes) as a CF endpoint #5489), which have no refresh and always end in expiry. (The issue text said expired → Disconnected flatly; that would have flapped every idle CF endpoint, hence the renewable gate.)

Sorting

• Cards order by favorites group → endpoint type (renderPriority) → natural name (cf1 < cf2 < cf10; previously payload map order).
• A direction icon attached to the segmented control flips the name order, tooltip explains what is sorted; direction never reorders groups or types. Persisted per user with the other Home prefs.
• A divider separates the endpoint controls from the layout menu, which is back to column presets only.

Card layouts

• Home cards gain a per-endpoint layout choice (homeCard.linksBelow): kubernetes renders its counts as a horizontal tile row with a Favorites/Shortcuts strip below; CF keeps the classic right-hand sidebar. Kube shortcuts moved to the definition level (like CF); the old in-card conditional shortcuts (Open Terminal / View Dashboard) needed async checks the sync definition hook can't express and remain reachable from the kubernetes pages.
• Shortcut links wrap inside their column instead of overflowing the card edge.
• Fixed a card double-render race (ngAfterViewInit + input rebind both creating the card while its lazy chunk import was in flight) — regression spec included.

Testing

• 27 unit tests across home page, endpoint card, kube card, and dashboard prefs (mode filtering incl. ethereal favorite groups, expiry/renewable presentation, sort tiebreak + direction, pref migration, double-create race).
• Full gate (lint + unit + production build + backend tests) green locally.
• Live-verified against a dev stack with 4 CF + 5 kube endpoints: starred+disconnected card, korifi-shape expired token (refresh blanked in DB), renewable expiry staying connected, Connect dialog round-trip, mode switching, sort direction, card layouts at single/two/three-column widths.

Closes #5588
