event-modal: port 4-channel Chart.js waveform/histogram panels

Adds inline waveform plots to the shared event-detail modal, ported
from sfm/sfm_webapp.html:2555-2880.  The standalone SFM webapp's
plot logic moves into event-modal.js with Tailwind-friendly grid +
tick colors (theme-aware via the `dark` class on <html>).

Channels render in BW Event Report order — MicL on top, Tran on
bottom.  Mic channel auto-converts psi → dB(L) when the operator's
mic_unit_pref is "dBL" (the default), using _psiToDblForChart with
a MIC_DBL_FLOOR=60 floor so the chart shows an SPL-vs-time curve
instead of a sparse pattern of "moments above floor".

Histograms render as bars with HH:MM:SS x-axis labels when the
sidecar carries time_axis.interval_times (events ingested with the
v0.20 parser); falls back to interval index for older events.
Geo + mic histogram channels enforce minimum Y ranges (0.05 in/s
and 0.001 psi respectively) so quiet events don't fill the panel.

Waveform events get the trigger-line + zero-baseline overlay; the
histogram branch suppresses it (no trigger concept).  Downsampling
kicks in at >3000 samples to keep render time bounded.

Modal partial widened max-w-3xl → max-w-5xl to fit the chart panels
without horizontal clipping.  Chart.js 4.4.1 loaded from cdn.jsdelivr
at the bottom of the partial, matching the standalone webapp's
reference version pin.

Side-yard: docker-compose bind-mounts ../seismo-relay-prod-snap into
the SFM container so the symlinked DB + waveform store inside
bridges/captures resolve.  Without it SFM 500s on every /db/* call
because the symlink target was outside the container's filesystem
view.  Read-write (not :ro) because SFM opens the DB in WAL mode
which requires creating -wal and -shm sidecar files even for reads.
