Support access schedule management for Matter DoorLock

[lboue]

Describe the enhancement

Home Assistant 2026.4 added Matter lock user and credential management (home-assistant/core#161936), but scheduling was explicitly out of scope for that phase ("Scheduling etc can come later").

The Door Lock cluster (0x0101) defines three access-schedule features with no HA-side support today:

• Week Day (WDSCH) — recurring weekly access windows per user
• Year Day (YDSCH) — fixed date-range access per user
• Holiday (HDSCH) — lock-wide holiday schedules with an associated operating mode, no per-user index unlike the other two

All three are already shipping on certified locks — e.g. the Aqara Smart Lock U400 exposes all three (WDSCH, YDSCH, and HDSCH), per real device telemetry: https://matter-survey.org/device/aqara-smart-lock-u400-4447-10244.

Device or feature details

Door Lock (device type 0x000A), Door Lock cluster (0x0101, ClusterId 257) — access schedule features:

• WeekDayAccessSchedules (WDSCH)
• YearDayAccessSchedules (YDSCH)
• HolidaySchedules (HDSCH)

Reference device with all three active: Aqara Smart Lock U400 — https://matter-survey.org/device/aqara-smart-lock-u400-4447-10244

Use cases

Extend the existing Matter lock manager (services + "Manage lock" panel) with schedule support, gated independently per feature on the lock's FeatureMap so a lock supporting only some of them still gets a working UI:

• Entity services aligned with SetWeekDaySchedule/GetWeekDaySchedule/ClearWeekDaySchedule (and Year Day / Holiday equivalents), following the same service pattern used for user/credential management in #161936
• Per-user schedule sections in the frontend panel for Week Day and Year Day, fed by walking existing users rather than a separate lookup
• A lock-wide section for Holiday schedules (no per-user index)
• A "clear all" action per schedule type (schedule index 0xFE)
