Display timestamps in Tehran time, not UTC

The server clock is correct (UTC); the app rendered UTC wall-clock directly, so
the run log showed ~3.5h behind Tehran. Add JalaliDate.ToTehran (flat UTC+3:30 —
Iran dropped DST in 2022) + DateTimeLabel, and convert the UTC-stored timestamp
displays (ingestion run log, RawListing FetchedAt, report CreatedAt). Shift
start/end inputs are TimeOnly, left as-is.
