fix: email poller marks calendar extraction processed on LLM failure (#4622)

Move calendar processed-marker insert into the LLM success path (else branch).
Previously, the INSERT ran even after a transient LLM failure, causing the
poller to skip retrying calendar extraction on subsequent runs.

Minimal change: only touches the try/except/else control flow in
_auto_summarize_pass_single() — preserves existing formatting and line endings.
