Add API server monitor in Studio (#5558)
* Add Studio API activity monitor

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Mark disconnected monitor streams cancelled

* Fix monitor lifecycle, parsing, and clock issues for PR #5558

Backend:
- Finalize the monitor entry as error on the chat-completions validation
  reject paths (addresses the codex P2 comment around line 2337). Adds a
  small _reject helper next to the api_monitor.start so each early-raise
  in the GGUF tool-passthrough, non-empty-messages, GGUF vision/audio,
  PIL image decode, and text-only model branches no longer leaves the
  entry stuck running until eviction.
- _monitor_openai_chunk is now defensive about malformed shapes
  (non-list choices, non-dict choice/delta) so a misbehaving provider
  chunk does not raise into the streaming generator and abort the
  user's response.
- _monitor_openai_sse_line accepts both data:value and data: value per
  SSE spec; previously the single-space-only prefix silently dropped
  tokens from compact emitters.
- openai_completions stream now keeps a residual buffer between
  aiter_bytes chunks so a data: line whose newline lands in the next
  TCP frame is reconstructed before parsing, instead of being dropped
  by the per-chunk splitlines call.

api_monitor:
- duration_ms is derived from time.monotonic anchors and clamped at 0,
  so NTP / manual clock steps no longer produce negative durations.
- finish() and fail() are idempotent: a second call (for example [DONE]
  arriving after the generator's finally block already ran) no longer
  moves finished_at or finished_monotonic.
- set_usage only derives total_tokens when no authoritative total has
  been recorded, so a later partial-usage chunk does not clobber a
  provider-reported total from an earlier chunk.
- _trim guards limit < 3 so the slice cannot underflow.

Tests:
- Adds regression coverage for the new idempotency, total preservation,
  monotonic clock, and _trim guard behaviour.
