feat: remove spp_hxl and spp_hxl_area modules

Remove the HXL modules. spp_gis_indicators was the only dependent; keep it
installable by dropping the hxl dependency and disabling the indicator-data
feature until a replacement source is wired in.

- Delete spp_hxl and spp_hxl_area.
- spp_gis_indicators manifest: replace spp_hxl_area with spp_cel_domain and
  spp_hazard (the variable_id/incident_id fields previously reached the module
  transitively via spp_hxl_area). Bump version 19.0.2.0.0 -> 19.0.3.0.0
  (breaking: dependency change + indicator-data feature disabled).
- Stub spp.gis.indicator.layer._get_indicator_values() -> [] and
  get_feature_colors() -> {} with TODOs; color scales, manual-break
  classification, and legend rendering remain functional.
- Rewrite hxl-coupled tests to assert the disabled contract; drop label/
  description keys from spp.cel.variable creates (those fields came from
  spp_studio via the removed hxl->spp_studio dependency, and the module's
  production code never used them).
- Regenerate requirements.txt: drop libhxl (was required only by spp_hxl_area).

Note: module readme fragments (DESCRIPTION/USAGE) are intentionally left
unchanged here and will be updated in a follow-up, to avoid triggering the
readme generator (which needs pandoc, currently missing in CI). See PR #230.

Tests: ./spp t spp_gis_indicators -> 84 passed, 0 failed, 0 errors.
