feat(studio): hardware-aware model recommendations + sidebar clock (v0.14.0)

System-AI editor now fetches the detected hardware tier and the
hub's curated model database on open. Each model chip's colour
+ tooltip combines both: green star when curated quality is
good/excellent AND min_hw_tier ≤ host; orange when quality is
fine but the host is below min_hw_tier; warning for "basic"
curated entries. Tooltip exposes the curator's note, parameter
count, context window, and licence. Banner above the form
shows "Detected: <summary> · curation reviewed <date>".

Sidebar footer gains a small monospaced live clock between the
theme toggle and the settings icon. Tooltip exposes full local
ISO + UTC for cross-checking against audit-log timestamps.
