Gud Boi 50f40f427b Include `TransportClosed` in tpt-layer err handling
Add `TransportClosed` to except clauses where `trio`'s own
resource-closed errors are already caught, ensuring our
higher-level tpt exc is also tolerated in those same spots.
Likely i will follow up with a removal of the `trio` variants since most
*should be* caught and re-raised as tpt-closed out of the `.ipc` stack
now?

Add `TransportClosed` to various handler blocks,
- `._streaming.MsgStream.aclose()/.send()` except blocks.
- the broken-channel except in `._context.open_context_from_portal()`.
- obvi import it where necessary in those ^ mods.

Adjust `test_advanced_faults` suite + exs-script to match,
- update `ipc_failure_during_stream.py` example to catch
  `TransportClosed` alongside `trio.ClosedResourceError`
  in both the break and send-check paths.
- shield the `trio.sleep(0.01)` after tpt close in example to avoid
  taskc-raise/masking on that checkpoint since we want to simulate
  waiting for a user to send a KBI.
- loosen `ExceptionGroup` assertion to `len(excs) <= 2` and ensure all
  excs are `TransportClosed`.
- improve multi-line formatting, minor style/formatting fixes in
  condition expressions.
