api-access, models: document gateway behaviour verified against the live API (fallbacks, reasoning defaults, usage, tool support)

Checked on 2026-10-19 with a member key. api-access.md gains a closing
section on what the gateway guarantees and what it doesn't: the fallback
chain and the headers that reveal it, per-call cost headers, timeouts and
retries, reasoning on by default on the Tinfoil models and how to turn it
off, dropped parameters, usage fields, /model/info and /team/info being
readable with a member key, the budget-exceeded shape, and the absence of
rate limits, body caps and an uptime guarantee. models.md gains a Tools
column (three of four tested models make tool calls; greenpt/glm-5.3
returns empty through the gateway, 3 of 3 runs), fallback and
reasoning notes on the affected rows, and a quick-guide fix.
