Add device config for Arlec/Deta EV200D-HA EV charger (#6088)

Adds a dedicated device profile for the Arlec/Deta EV200D-HA EV charger
(22kW/32A, 3-phase), which is currently unsupported and incorrectly
matches `tera_w01_evcharger`: wrong min current (this hardware supports
6A, not 8A) and missing several DPs the Tera profile doesn't define.

Related issue: #6087, filed with the full cloud DP dump, local DPS
captures, and notes on what's confirmed locally vs still guesswork.

This profile matches on product_id `svufayckw5hozqbz` (the device's own
cloud "thing" dump; firmware self-identifies as `H0_ARLEC-V1.0.6`),
corrects the charge current range to 6-32A, keeps all the Tera-profile
entities this hardware also supports, and adds entities for the DPs this
device exposes that Tera's profile doesn't: single-phase power (DP5),
session energy (DP25), meter ID (DP22), dynamic load management switch
(DP101), home max current (DP102), solar mode (DP103,
read-only/diagnostic since the full enum isn't confirmed), solar current
from grid (DP104), and solar stable time (DP105). DPs I couldn't confirm
safely from local capture alone (11, 12, 15, 16, 17, 19, 27, 33) are
deliberately left unmapped rather than guessed.

Testing: validated with the integration's own matching code
(TuyaDeviceConfig.matches() / possible_matches()), where this profile
scores 101 against the real device's DPS vs 59 for tera_w01_evcharger
(today's fallback match). Also ran it live against the physical device:
switched a running Home Assistant instance onto this profile, confirmed
all entities (existing and new) report correct values, and confirmed the
corrected 6A minimum actually works on the hardware.

I'm aware PRs are currently paused. Opening this anyway at the device
owner's request, since the fix is tested and the corresponding issue is
already filed. Happy to wait for review whenever bandwidth allows, and
to make any changes requested.
