  PIPE-3085: Extend MS open optimization to `correctedampflag`, `rawflagchans`, `gcorfluxscale`
  Hoist casa_tools.MSReader outside the inner loops in three additional
  tasks, following the same pattern established for hif_applycal weblog
  rendering:
  
  - hif_correctedampflag: open once for the intent × field × spw loop
    in _run_flagging_iteration; thread ms_handle through
    _evaluate_heuristic → _evaluate_heuristic_for_baseline_set →
    mstools.read_channel_averaged_data_from_ms.
  - hif_rawflagchans: open once for the spw loop in
    RawflagchansData.prepare; call openms.reset() between iterations
    instead of opening a fresh handle per SPW.
  - hifa_gfluxscale: open once for the field × spw loop in
    _derive_calvis_flux; pass ms_handle to mstools.compute_mean_flux.
  
  Also: bare except: → except Exception:, lazy % log formatting.

  PIPE-3085: Reduce MS open overhead in `hif_applycal` weblog rendering
  Reduce the cost of opening measurement sets in get_brightest_field()
  by reusing a single MS handle across all (field, spw) iterations instead
  of opening and closing the MS once per combination. On lazy-import data
  sets, where the DATA column is ASDM-backed, this cuts the applycal
  post-processing time significantly (observed ~50 min saving on a
  2496-call dataset).
  
  - renderer.py: open MS once with casa_tools.MSReader and pass handle
    down to mstools.compute_mean_flux via the new ms_handle kwarg.
  - mstools.py: add keyword-only ms_handle parameter to both
    read_channel_averaged_data_from_ms and compute_mean_flux; call
    openms.reset() before each reuse to clear prior selection state.

  PIPE-3085: hifa_fluxcalflag - cache SPW freq grids and use searchsorted in _get_chanrange
  Open the MS once per prepare() call instead of once per line candidate,
  and cache the cvelfreqs result per (vis, fieldid, spwid, refframe) via a
  new _get_spw_freqs helper. Replace the O(N) linear channel scan with
  np.searchsorted for O(log N) boundary lookup. Also convert %-style LOG
  calls to lazy-format style and raise ValueError instead of Exception.
