bee_hotel 2.28.0

Summary
-------

This release adds a JSON import pipeline for special_night nodes and
fixes a date range matching bug in the SpecialNights Price Alterator
that caused special prices to be silently ignored.

New features
------------

- JSON import for Special Nights.

Two Drush commands are now available:

- drush bhpas:check
Validates the configuration and prerequisites without writing to
the database.

- drush bhpas:import
Creates or updates special_night nodes from JSON files, matching
on the (field_nights.value, field_room.target_id) pair. Supports
--dry-run, --force and --source-dir options.

The import is idempotent: running it multiple times updates the
existing nodes instead of creating duplicates.

- New configuration fieldset "Import from JSON" in the Special Nights
alterator settings, exposing the source directory, nights/adults,
primary and secondary channel discounts, and imported node status.

- Sample JSON fixture at tests/fixtures/special_night_example.json,
with a format reference in tests/fixtures/README.md.

Bug fixes
---------

- Fixed: the SpecialNights plugin did not match nodes whose check-in
was stored at 23:00 and check-out at 22:59, because the query
compared against T00:00:00 and T23:59:59. As a result, special
prices were never applied to the room calendar. The date range
conditions have been corrected.

Upgrade notes
-------------

No database updates are required. After updating the codebase:

drush cr
drush bhpas:check

If you were already using a previous import implementation, open the
"Import from JSON" fieldset in the Special Nights form and re-save it
to migrate the configuration keys to their new names
(import_discount_primary, import_discount_secondary).
