Python: Fix spurious Magentic custom manager warning (#6261)

* Fix magentic manager warning

* Use typing_extensions.Sentinel for _MISSING sentinel value

Replace the bare object() sentinel with typing_extensions.Sentinel per
PEP 661 (now final). Sentinel provides a proper name and repr
('<_MISSING>') and is the idiomatic approach going forward.

* fix: correct Sentinel type annotation for max_stall_count param (#6261)

Use int | Sentinel for max_stall_count parameter type annotation instead
of int with cast(Any, _MISSING) to properly express that the parameter
can hold either an int or the _MISSING sentinel value. This fixes the
pyright reportUnnecessaryComparison errors caused by the types int and
Sentinel having no overlap.

* Rename _MISSING sentinel to UNSET in orchestrations

The sentinel is user-visible as a default in public init signatures, so
use UNSET (no leading underscore) instead of the private _MISSING name.
Drop the now-unnecessary reportPrivateUsage ignores on the UNSET imports.
