Marc Billow fa8f1b8675 Add cool-only global RAC support: WindFree, Auto mode, display light
Finishes PR #91's contribution (pedroperosin) with the requested review
changes applied, on our own branch:

- Preset resolution is now fully dynamic, read from each unit's own
  /mode/convenient/vs/0 supportedModes instead of a static per-model
  table -- any board's convenient modes (including WindFree's Nano/
  NanoSleep) surface without code changes. Unlabelled codes across
  existing fixtures (longwind, motionindirect, motiondirect, drycomfort)
  plus the two new WindFree ones are added to en.json/nl.json.
- 'Auto' now maps to HVACMode.AUTO instead of HEAT_COOL: these are
  single-setpoint "device decides" units, not two-setpoint heat+cool
  ones. 'Fan' is added alongside 'Wind' as a second FAN_ONLY spelling;
  a new _device_code_for_hvac() picks the code from the unit's own
  supportedModes since the flat map can't disambiguate two device codes
  mapping to one HA value.
- Detection gains a hyphenated '-RAC-' modelNum fallback (alongside the
  existing '_RAC_') for cool-only global RAC variants whose
  /otninformation/vs/0 ships no swVersionInfo block.
- Adds a display_light switch sourced from /mode/vs/0's opaque options
  blob (inverted Light_On/Light_Off token) for boards with no dedicated
  /light/vs/0 switch.

Write-path behavioural change (touches the path iterated on across
#9/#17/#27/#38/#54): power now targets the vendor /power/vs/0 instead of
the OCF /power/0, and _is_on() reads vendor-first. /power/0 is absent on
several known AC boards, so the previous OCF-first read/write pair could
report and act on stale state -- consistent with #53's "can turn on but
not off". Target temperature now picks its channel (OCF pair vs. vendor
items[]) based on which the unit actually reports, reading and writing
the same one.

The vendor temperature write and the new display-light write both carry
only the changed field(s), not the whole resource -- confirmed sufficient
on the wire, the device merges the rest itself. That requires the
coordinator's optimistic cache to do the same merge on the read side so a
setpoint change doesn't blank out current/min/max/unit for the settle
window: common.py gains merge_items_field() next to the existing
merge_options_field(), and async_send_command wires it in for any write
touching x.com.samsung.da.items.

New fixture/golden for the cool-only global RAC variant (TP1X_DA-AC-RAC-
01001, AI_RAC_GLOBAL_COOLONLY_3.0); display_light added to the goldens
for boards that gain the new options-based switch. Regenerated against
current main rather than copied from the original PR, since those
goldens had already shifted (current_temperature_c/humidity from issue
#75).
