fix(import): overlay BW report onto Event + upsert DB row on re-import

Two compounding bugs caused forwarded events to land in the DB with
broken-codec peak values (~10 in/s saturation on every channel) and
no project info, even when the watcher correctly paired a BW ASCII
report with the binary.

Bug 1: save_imported_bw built the sidecar JSON with the report's
authoritative peak / project values via event_to_sidecar_dict(
bw_report=...), but never overlaid those onto the in-memory Event
that flows to db.insert_events().  So the DB row got peak_values
from read_blastware_file()._peaks_from_samples() — which runs the
still-undecoded waveform body codec assuming raw int16 LE and
produces ±32K-shaped noise (= ±10 in/s at Normal range) regardless
of the actual signal.  The sidecar JSON had the truth but the DB
columns (which the webapp queries for fast filter/sort) lied.

Bug 2: insert_events' IntegrityError handler only refreshed the
filename/filesize/a5_pickle/sidecar columns when a duplicate
(serial, timestamp) was seen.  Peak values, project info,
sample_rate, record_type stayed locked in at whatever the FIRST
insert wrote.  So even after Bug 1 was fixed, the historical
events in the DB (already inserted with broken-codec peaks) would
never get their values corrected, because a re-forward would just
hit IntegrityError and skip the field refresh.

Fix 1 (minimateplus/event_file_io.py + sfm/waveform_store.py):
  - New apply_report_to_event(event, report) helper folds the BW
    report's device-authoritative fields onto the Event in-place:
    per-channel PPV, peak vector sum, mic PSPL→psi, project /
    client / operator / sensor_location, sample_rate, record_time.
  - save_imported_bw() calls the helper right after parsing the
    report.  The Event that flows to insert_events() now carries
    correct values.

Fix 2 (sfm/database.py):
  - insert_events()'s IntegrityError UPDATE now refreshes every
    device-authoritative column from the new data: tran_ppv,
    vert_ppv, long_ppv, peak_vector_sum, mic_ppv, project, client,
    operator, sensor_location, sample_rate, record_type, plus
    the existing filename/filesize/a5_pickle/sidecar fields.
  - Preserves: id, waveform_key, session_id, created_at (immutable
    / FK fields), and false_trigger (operator review state).

End-to-end simulation verified:
  - Step 1: import without report → DB has ±10 in/s peaks, no project
  - Step 2: re-import WITH report → upsert path fires, DB now has
            device-authoritative 0.005 in/s peaks + sensor_location
  - Step 3: operator sets false_trigger=1, re-import again → flag
            preserved, peaks remain correct

For the user's situation: deleting the watcher state file forces a
re-forward of all events.  Each re-forward now pairs with its
_ASCII.TXT, applies the report onto the Event, and the upsert
refreshes the DB row.  No DB nuke needed.
