Subject: [PATCH 07/27] Add STOQS permalink to LRAUV deployment HTML index

- Refactor make_permalink: add stoqs_url_from_ds() and
  lrauv_stoqs_base_url() to generate a STOQS "Share this view" URL
  directly from an xarray Dataset; switch gen_permalink() from a
  parameter-id/clicks model to a platform_clicks selector; fix
  get_parameter_id() URL construction (Path() was mangling the
  query string)
- Refactor lrauv_deployment_plots: extract _build_and_write_html()
  from plot_deployment(); call stoqs_url_from_ds() and pass the
  resulting URL (or None on failure) to _write_html(); add a STOQS
  section with a "Share this view" link to the generated HTML
- Add OPeNDAP data-access-form (.nc.html) links for each log file
  in the HTML index
- Enable parallel/chunked open_mfdataset() with dask
- Fix np.linspace int cast in create_products.py
- Add dask and lzstring to pyproject.toml dependencies
- Update tests: fix test_platform_id_in_permalink (platform_clicks
  key, platform name); fix test_stoqs_failure_still_writes_html
  (patch stoqs_url_from_ds directly)

Subject: [PATCH 17/27] Add time-range and batch execution options to
 lrauv_deployment_plots.py

Replace the single required --dlist argument with a mutually exclusive
group supporting three execution modes:

  --dlist DLIST
      Process a single deployment by .dlist path (previous behaviour).

  --last_n_days N
      Discover and process all deployments whose date-range directory
      falls within the last N days.

  --start YYYYMMDD [--end YYYYMMDD]
      Process all deployments overlapping the given date range.
      --end defaults to today when omitted.

  --auv_name NAME
      Restrict the dlist search to a single AUV (used with
      --last_n_days or --start/--end).

Add _dlist_list() to scan the LRAUV_VOL mount point (falling back to
BASE_LRAUV_PATH) for YYYYMMDD_YYYYMMDD directories within the requested
window, returning the sibling .dlist file for each matching directory.

In plot_deployment(), validate the deployment directory against both
BASE_LRAUV_PATH and LRAUV_VOL, and create the local output directory
with mkdir(parents=True) so PNGs and HTML can be written even when the
processed .nc files live only on the mounted volume.
