Previously only showed import cost by tariff period; now also shows the
feed-in/export credit components alongside it, plus a net (usage cost
minus export credit) total.

Cost modeling can't tell you whether you actually qualify for a plan --
several top-ranked results turned out to require things like buying
solar equipment through a specific installer partner, or being a new
customer only. AER's data states these restrictions explicitly in most
cases; surface them as modeling notes (and a badge in the comparison
table) so they're visible before considering a switch, rather than
only showing up when someone tries to sign up.
Doesn't catch every restriction -- some plans (e.g. concession/seniors
offers) carry no eligibility block in AER's data at all despite an
implied real-world restriction, so absence of the badge isn't a
guarantee of eligibility.

Confirmed against Sungrow's own docs and live-tested against a real
battery plant: SOC and charge/discharge power live at the *device*
level (getDeviceRealTimeData against the hybrid inverter's ps_key,
device_type 14), not in the plant-aggregate points used elsewhere in
this client -- querying them via the plant-level endpoint just returns
null. Battery status is fetched once per live "today" poll (not
backfilled historically) and stored in three new nullable columns,
self-migrated on startup since there's no Alembic here.
Also fixes the dashboard's self-consumption line to derive from
load - import rather than generation - export, which overstated
"solar -> house" for battery systems (a chunk of that gap was going
into charging, not the house). The live flow diagram now shows a
Battery node (SOC + charge/discharge) that stays hidden entirely for
solar-only plants like Kallangur.

New /api/usage/live endpoint derives instantaneous-ish kW from the most
recent interval reading, shown as a solar -> house/grid flow diagram
that updates every 30s and flips direction/color between exporting and
importing. /api/usage/summary now also reports net revenue for the
selected period, reusing the existing costing engine against the
current plan.

Settings always showed the full "how to connect" steps and code-paste
form for oauth2 mode regardless of connection status, which read as
broken even when the token was live and polling successfully. Collapse
it behind a "Reconnect" toggle once connected.

FastAPI app that pulls interval usage from Sungrow iSolarCloud (OAuth2),
caches AER Consumer Data Right electricity plan data, and compares actual
metered usage against every available plan to estimate real annual cost
(TOU, tiered feed-in, and flat tariffs).
