feat: support App login and align device controls

[wangty163]

Summary

• reproduce the current Haier Smart Home App account/password token exchange
• persist only generated client IDs and returned tokens; never persist account passwords
• normalize numeric Haier user IDs to strings and migrate existing entries for Home Assistant compatibility
• align entity names, program options, value ranges, and entity platforms with the current official App configuration for the verified dishwasher and refrigerator models
• add missing device controls, including dishwasher stop/reservation/App settings and refrigerator temperature/time controls
• read the dishwasher settings list dynamically so Home Assistant follows the names and switches currently exposed by the App backend
• exclude mall, customer service, account management, unsafe engineering commands, and model attributes that are not exposed by the verified App product profile

Entity semantics

• expose dishwasher and refrigerator door states as binary_sensor entities with the door device class
• remove the malformed writable dishwasher doorStatus attribute and use the real read-only doorCloseStatus
• expose one-shot power and refrigerator purification commands as buttons
• separate dishwasher running state from running control
• invert buzzerDisabled so the Home Assistant “蜂鸣音” switch matches the App meaning
• migrate stale or platform-changed entity registry entries before platform setup

Device impact

• Casarte CWC10-B29BKU1: six official wash programs, stop, reservation, drying, disinfection, enhance, rinse, power, remote authorization, buzzer, water-softener and rinse-aid levels, plus App reminder/AI/hot-wind/peak-valley settings
• Casarte BCD-450WGCFDM4WNU1: refrigerator/freezer temperature controls, baby-care compartment, smart storage, quick freeze, travel energy saving, purification, time-of-use settings, and four door-state sensors

Validation

• real account/password login confirmed in Home Assistant by the user
• 23 unit tests pass inside the live Home Assistant 2026.7.4 container
• 54 Python files compile and git diff --check passes
• current device digital models and official App cloud/configuration APIs were audited read-only against the live account
• all 27 live integration files exactly match the release tree hash
• after the beta.4 restart, 74 Haier entities load with the expected domain distribution; 43 key App/semantic entities match their required names and platforms, with zero unavailable entities
• all five door entities report device_class=door and the current closed state
• Home Assistant is healthy with restart count 0 and no Haier startup errors
• no device control command was sent during validation

Deployment

Release v1.3.0-beta.4 is installed through HACS from wangty163/haier at commit 4d73260; the integration was not manually copied into the live Home Assistant configuration.
