fix: respect hide_pins on child lock parent-view dashboard

[raman325]

Summary

• Fixes ISSUE: Hide Pin Not working on Child Lock v.0.3.0 (similar to Issue #476) #597: child lock dashboard showed parent's PINs in plaintext even when hide_pins was enabled on both locks.
• When hide_pins is true, removes the simple-entity PIN row from the parent-view entities card and adds a read-only Jinja2 markdown card (via vertical-stack) showing "Slot occupied" / "Empty" instead.
• Extracts resolve_entity_id() from the _map_property_to_entity_id pipeline so callers can resolve individual property paths to real HA entity IDs without the full recursive mapping.

Why

The child lock's parent-view card (shown when override_parent is off) used type: simple-entity for all parent entities including the PIN. The simple-entity card type renders the raw entity state, bypassing TextMode.PASSWORD masking — so PINs were visible on the child dashboard even when hide_pins was enabled.

The default text entity row can't be used either because it has inline editing that tap_action: none doesn't block. A markdown card is read-only by nature, uses no custom card dependencies, and uses Jinja2 to show occupancy status without revealing the PIN value. Since markdown is a card type (not a valid entities-row type), it's placed alongside the entities card in a vertical-stack.

Test plan

• pytest --no-cov -q — 648 passed
• test_generate_view_config_child_lock_hide_pins — verifies vertical-stack structure: entities card (no PIN row) + markdown card with "Slot occupied"/"Empty" template
• test_generate_view_config_child_lock_no_hide_pins — verifies entities card keeps simple-entity PIN row, no vertical-stack
• Manual verification on a child lock dashboard with hide_pins enabled

Pull request overview

Fixes a security/privacy leak where a child lock’s parent-view dashboard could display the parent lock’s PINs in plaintext despite hide_pins being enabled.

Changes:

• Updates child-lock parent-view generation to replace the parent PIN row when hide_pins=True.
• Adds tests covering hide-pins vs non-hide-pins behavior for child lock parent-view.
