fix(browserless): reject timeouts httpx cannot use (#8025)
* fix(browserless): reject timeouts httpx cannot use

`_coerce_timeout` forwarded any int, float or numeric string to
`httpx.AsyncClient(timeout=...)` unchanged, so a configured `timeout_s: 0`
or a negative value failed every fetch and capture with `ConnectTimeout`
against a healthy backend, `nan` raised `ValueError: deadline must not be
NaN`, and `inf` left the request without a deadline so it never completed.
Each of those silently disabled the provider.

Fall back to the documented 30s default with a warning when the number is
not a usable deadline. This matches `crawl4ai._coerce_timeout` after #7481;
`jina_ai._coerce_timeout` still forwards non-positive values.

* fix(browserless): address timeout review and format tests

Explain how HTTPX handles NaN and positive infinity. Document that
Browserless accepts positive finite timeouts without an upper limit,
and pin that behavior with a 1e308 test case.

Crawl4AI and Jina timeout validation are tracked in #7481 and #7823.
Remove the Browserless docstring's claim that Crawl4AI shares its
coercion behavior. Format the test file for the backend lint check.
