fix: resolve UI glitches and improve consistency

- Sidebar: make +App button more subtle (lower opacity, brightens on hover)
- Sidebar: add filter chips to hide empty routes and offline/stale apps
- Sidebar: hide filter chips and +App button when sidebar is collapsed
- Exchange table: reorder columns to Status, Attributes, App, Route, Started, Duration; remove ExchangeId and Agent columns
- Exchange detail log tab: query by exchangeId only (no applicationId required), filter by processorId when processor selected
- KPI tooltips: styled tooltips with current/previous values, time period labels, percentage change, themed with DS variables
- KPI tooltips: fix overflow by left-aligning first two and right-aligning last two
- Exchange detail: show full datetime (YYYY-MM-DD HH:mm:ss.SSS) for start/end times
- Status labels: unify to title-case (Completed, Failed, Running) across all views
- Status filter buttons: match title-case labels (Completed, Warning, Failed, Running)
- Create app: show full external URL using routingDomain from env config or window.location.origin fallback
- Create app: add Runtime Type selector and Custom Arguments to Resources tab
- Create app: add Sensitive Keys tab with agent defaults, global keys, and app-specific keys (matching admin page design)
- Create app: add placeholder text to all Input fields for consistency
- Update design-system to 0.1.52 (sidebar collapse toggle fix)
