Observe: activity, logs, performance, KV cache

The Observe page has four tabs, plus a shared time window (5 min / 15 min / 1 hr / All) that filters Activity rows and trims the Performance charts.

• Activity: per-request history. Summary tiles at the top (requests, cache hits, tokens processed and generated, median speed) with prompt-processing and token-generation histograms; below them a table you can filter by model / path / status, with a column picker you can reorder - id, time, model, path, status, content type, cached, prompt and generated tokens, prompt t/s, gen t/s, duration. Click a row's capture to open the full request/response body.
• Logs: live logs, shown as Both, Proxy only (Quartermaster's own lifecycle log) or Upstream only (the backend's raw stdout). Each panel has a regex line filter, text wrap, and copy.
• Performance: charts over time - GPU utilization, GPU memory, temperature (plus VRAM temperature and power draw where the card reports them), per-core CPU, memory and swap, load average, and network bandwidth. The refresh interval is selectable (off / 5s / 10s / 30s / 60s).
• Context: two panels. KV Cache shows the live slots, the saved snapshot files, preamble mints, restore success rate, disk usage and recent save/restore activity (see the KV-cache article). Prompt Canonicalization shows how many requests were rewritten to a stable prefix, how many bytes that trimmed, and the recent rewrites.

Live metrics stream over SSE, so the page updates in real time while a model generates.
