Sunsynk/Deye Freeze Export fixes

What's Changed

Sunsynk and Deye cloud

Freeze Export was a silent no-op on both Sunsynk and Deye. Predbat signals it by turning the forced-export window off and zeroing the charge rate, but that rate maps to a per-window control that a disabled window never reads — so the inverter was left in ordinary self-use and surplus solar charged the battery instead of being exported. The freeze state meant to catch this was unreachable, and would have written Predbat's internal "99" freeze marker as a battery SoC target, telling the inverter to drive the battery to 99%.

A freeze export now writes Selling First with the per-slot Sell flag on, a zero sell rate and the cap at the reserve — verified against live hardware, including the controlled pair that identifies the slot rate as the sell-rate cap (at full rate the battery drained to the grid at up to 4.7 kW; at zero it held while surplus solar still exported).

• fix(sunsynk): make Freeze Export actually reach the inverter
• fix(deye): apply the same fix to the same registers
• docs(sunsynk,deye): correct what a zero slot rate actually does
• Resolves the Sunsynk grid_power sign verification — no behaviour change, now pinned to a live sample and a regression test

Both components' freeze charge behaviour is unchanged.

Note for Deye users: the Deye half is applied on register parity with Sunsynk (both clouds drive the same Deye registers) but has not itself been confirmed against live Deye hardware. If your Deye battery exports during a Freeze Export slot, please raise an issue.

Fix Solis crash that prevented any plan being produced

What's Changed

A single-fix hotfix for Solis users. If you have a Solis inverter, upgrade from v8.48.4 immediately —
on most Solis installs v8.48.4 cannot produce a plan at all.

Bug fixes

The nominal_voltage fix in v8.48.4 (#4502) added a once-per-inverter warning for installs where the
battery capacity has to be estimated from the live measured voltage. The set that tracked which
inverters had already been warned was never initialised on the real component, so the first
publish_entities() run raised:

Error: SolisAPI: 'SolisAPI' object has no attribute 'capacity_voltage_warned'

That aborted the update cycle, so Predbat kept trying to calculate and never produced a plan. The
warning sits on the branch taken whenever solis_nominal_voltage is not set in apps.yaml — which is
every install that has not explicitly configured it, so in practice this hit nearly all Solis users on
v8.48.4.

• fix(solis): initialise capacity_voltage_warned so publish_entities stops crashing by @springfall2008 in #4555

Setting solis_nominal_voltage in apps.yaml also avoids the crash and remains worth doing on its own
merits — it gives an accurate, stable battery capacity instead of one estimated from a voltage that
drifts with charge state.

Testing

The whole Solis test suite passed against a component that could not survive a single real poll, because
MockSolisAPI replaces __init__ wholesale and had stubbed the attribute the production path was
missing. A parity guard now constructs the real component and asserts it sets every attribute the mock
stubs, so this class of mock/real divergence fails in CI rather than on a live inverter.
