tliu93 8b91146c29 FU10: localize energy time math to server tz; accrue fixed/credit per elapsed local day
frontend / frontend (push) Successful in 2m5s
Details
pytest / test (push) Successful in 7m34s
Details 
- Store UTC, compute day boundaries in server local timezone (new app/services/timezone.py).
- summarize: fixed fee / tax credit accrue only for elapsed whole local days,
  integrated across contract versions — no future-day inflation, no version-switch collapse.
- MQTT import_cost_total / export_revenue_total getters delegate to summarize (no inline
  apportionment), anchored at the active contract's earliest version effective_from so the
  total sensors stay monotonic and never jump backward.
- effective_from: naive datetimes interpreted as server-local wall-clock, then stored UTC.
- frontend ContractForm sends local-midnight naive datetime (was UTC midnight).
- get_costs_summary default window uses server-local "today".

tliu93 d7f0731d1c ha_discovery: publish state/availability under home_automation prefix 
Follow the standard MQTT Discovery split: discovery config stays under the HA
discovery prefix (homeassistant/.../config, required), but the actual state and
availability are published under our own prefix (default home_automation/). The
config payload's state_topic/availability fields point at the new prefix so HA
reads state from there.

- new config ha_state_topic_prefix (default home_automation).
- build_discovery_payload + all publish_* split discovery_prefix (config topic)
  from state_prefix (state/availability). energy-cost still omits availability;
  modbus availability structure unchanged. Tests updated.

tliu93 9bc46f8d2d expose: buy/sell_price_now follow the live dual-tariff slot 
Subscribe the separate DSMR tariff topic (dsmr/meter-stats/electricity_tariff,
1=dal/off-peak, 2=normal/peak), keep the latest slot in memory, and make the
manual-contract buy/sell_price_now sensors show the matching tariff's price
(tariff 1 -> dal, 2/unknown -> normal). Tibber (single 15-min price) unchanged.
Billing is untouched (register-split already handles tariffs correctly).

- new config dsmr_tariff_topic; subscribe managed by apply_dsmr_subscription
  (restart-free on config save). In-memory tariff is lock-guarded.
- import_cost_total / export_revenue_total cumulative getters unchanged.

tliu93 6f8cb05eab expose: fold standing fee into import cost, tax credit into export revenue 
So HA can show the full payable: net = import - export = Total Payable, with
both entities staying monotonic-positive (no negative-value/reset pitfalls).

- import_cost_total = SUM(import_cost) + days*(network_fee+management_fee)/30
- export_revenue_total = SUM(export_revenue) + days*heffingskorting/365
  (days = calendar days since the active version's effective_from, incl. today)
- state_class total_increasing -> total (monetary-compatible; values still only
  increase). device_class/key/names: key unchanged, names clarified.
- buy/sell_price_now and DeviceInfo untouched. Decimal money math. Tests added.

tliu93 7e61b0a938 HA Discovery fix: energy-cost sensors are always-available 
The energy-cost device has only sensors (no online/offline heartbeat), but the
discovery config still declared an availability topic that nothing ever publishes
'online' to — so Home Assistant marked every energy-cost entity 'unavailable'
even though the state topic was being published (visible in MQTT Explorer).

- DeviceInfo gains provides_availability (default True, keeps Modbus behavior).
- _energy_cost_provider sets provides_availability=False.
- build_discovery_payload only emits availability/availability_mode for devices
  that publish a heartbeat; HA treats the rest as always-available.
- Test asserts energy-cost configs omit availability.

tliu93 c61fc2d4ba M6-T08: add energy_cost expose provider + post-billing state publish 
- expose.py: _energy_cost_provider yields buy/sell_price_now + import_cost_total
  /export_revenue_total (total_increasing, monetary), value_getters read from
  energy_cost_period; 2-element identifiers so the existing HA Discovery builder
  (which indexes identifiers[1]) works. Other providers/mechanism untouched.
- main.py: energy-cost job calls publish_states after computing periods (no-op
  when MQTT/Discovery off). Tests added.
Note: energy-cost sensors lack an availability heartbeat (ha_discovery mechanism
limitation, out of scope here).
