feat(laresar_l6_nex_vacuum): add Laresar L6 NEX robot vacuum and mop (#5421)

* feat(laresar_l6_nex_vacuum): add Laresar L6 NEX robot vacuum and mop

* fix(laresar_l6_nex_vacuum): use translation_keys for cleaning_mode and battery

* fix(laresar_l6_nex_vacuum): address PR review comments

- Move suction (DP9) into vacuum entity as fan_speed
- Move locate (DP11) into vacuum entity; remove Find robot button
- Remove battery_level from vacuum entity (deprecated HA 2025.8)
- Apply translation_key: mopping to water tank level (DP10)
- Apply translation_key: cleaning_mode to work mode (DP41) with sweep/mop/sweep_and_mop values
- Rename DP4 select to Cleaning pattern to avoid cleaning_mode conflict
- Remove readonly: true from all sensor dps (implicit for sensors)
- Remove name: Fault status from binary_sensor (name not needed)
- Add fault_code attribute to binary_sensor

* fix(laresar_l6_nex_vacuum): use mop_state as available constraint on mopping entities

Add DP40 (mop installed/none) as available dp to mopping select and mop
life sensor so they disable dynamically when no mop pad is attached.

* fix(laresar_l6_nex_vacuum): add command dp and activate/pause to vacuum entity

Wire DP4 (chargego) as the command dp for return_to_base, DP1 as activate
with pause-constraint logic, and DP2 as a hidden pause dp. Remove the
now-redundant Start cleaning, Pause, and Return to dock button entities.

* fix(laresar_l6_nex_vacuum): simplify activate/pause dps in vacuum entity

Remove the Pattern C constraint mapping from activate dp. The L6 NEX
reports paused state directly via DP5 status, so constraint-based
disambiguation is unnecessary. Simple boolean activate/pause works and
allows the vacuum card Start button to function correctly.
