… + cache-bust

The earlier fix only touched app.js, but index.html loads next-app.js —
app.js renders only on /legacy.html. So the live dashboard's charts kept
their hard-coded dark chrome and stayed dark/invisible in light mode.

Mirror the theme resolver (cssColor + cached chartColors) into next-app.js
and apply it to all canvas chrome: the power/energy chart (renderChart),
both hover tooltips, and the 24h battery+SoC live-history chart — axis
text, gridlines, zero/now/hover lines, tooltip bg+border+text, and the
neutral Load line. Saturated data-series hues are unchanged.

Bump the cache-bust tokens (next-app.js next19->next20, heating.js
heat1->heat2) so browsers actually re-fetch the updated next-app.js and
the already-shipped heating.js re-discovery fix instead of serving the
stale cached copies.

Each row in the per-driver 'all signals' drill-in now shows the signal's
source Modbus register id (m.register from the driver detail metrics, supplied
by the NIBE driver / emit_metric register plumbing). Signals with no Modbus
mapping render '—'. Bumps heating.js cache token heat2->heat3 so browsers pick
up the new column.

…tips

Replaces the 4-tile card with a grouped layout (Effekt & el · Temperaturer ·
Ventilation · Drift · Energi). Each tile shows the NIBE sensor designation in
parens (BT21, BE1, GP1 …) and an info icon whose hover tooltip explains the
term. Adds 'Total effekt nu' (whole-pump draw) distinct from compressor-only
power. Bumps heating.js heat3->heat4.

…power-limit tiles

Card labels, tooltips and group titles are now English. Priority shows a word
(Off / Hot water / Heating / …) instead of the raw code. The per-tile help
icon is a '?' circle matching the existing .plan-help-btn style (border, sizing,
accent hover) instead of the custom ⓘ. Adds Power limit / Fuse / Max add. heat
tiles. heat4->heat5.

Each group (Power & electrical, Temperatures, …) is now a distinct grey
sunken sub-card matching the dashboard's in-card box pattern (--ink-sunken +
--line border + radius + padding), so the groups read as separate cards under
the heat-pump card. heat5->heat6.

…form

The form treated NIBE as an OAuth (apicreds) driver and seeded
{client_id, client_secret}. Distinguish local basic-auth drivers (apicreds +
connection_defaults.port) and seed {host, username, password} instead. The HTTP
fieldset now renders Username + a Certificate fingerprint (tls_pin_sha256) field
for these drivers; password comes from config_secrets. allowed_hosts is
auto-derived from config.host by the backend (port-insensitive), so no manual
allowlist needed. devices.js tabsplit2->tabsplit3.

Step 2: a 30-day multi-line SVG chart (outdoor BT1 / supply BT2 / return BT3,
distinct hues, themed axis) under the tiles. Step 3: an Energy-per-period box
(Today / This week / This month / This year, consumed vs produced) computed
client-side as counter deltas across calendar boundaries; periods without enough
logged history show 'accumulating'. Both fetch via /api/series (needs the
generic parseRange added in the nibe branch for 30d/366d windows). heat6->heat7.

Each row in the All-signals detail now carries an always-visible sub-line
explaining what the signal is: the curated card-tile description when one exists,
otherwise the device's own point title (m.title, newly served by the API). Keeps
the 'All signals' button. heat7->heat8.

…fields

Card: clicking a ? help icon no longer navigates into the all-signals
detail (onGridClick ignores .ftw-hp-i); the native title tooltip explains the
metric in place. Devices tab: the local-HTTP Username + cert-fingerprint inputs
now use the same render-then-reveal pattern as the battery field, so they appear
for apicreds drivers (NIBE) even when the first render beats the async catalog
fetch — previously they were dropped. Tokens heat8->heat9, tabsplit3->tabsplit4.

The battery field was relying on the [hidden] attribute, which any author
CSS rule on .field-row children can override. Switch to an inline display:none
(beats any selector) on both the initial render and the post-catalog toggle, so
the NIBE heat-pump (catalog caps: apicreds, no battery) never shows it. Token
tabsplit4->tabsplit5.

The api blanks config.password but exposes a driver-level has_password
flag (config.go MaskSecrets). The Secrets badge only checked the blanked
config value, so a saved NIBE password showed as unset. Read has_password for
the password key. No backend change needed. Token tabsplit6->tabsplit7.

Replace the axis-less sparkline on the card with a dedicated powerChartBlock:
0-based kW y-axis + HH:MM time x-axis, reusing the temp chart's HTML-axis layout.
sparkline() is untouched so the ~937 tiny per-signal detail charts stay minimal.
heat10->heat11.

Co-Authored-By: HuggeK <[email protected]>

The ~937 detail sparklines were unlabelled. Add a compact per-sparkline
min/max (its y-scale) beside each, widen the trend column to fit, and note the
shared 24h window in a modal subtitle. sparkline() stays shared/minimal.
heat11->heat12.

…imestamp

Heat-pump card: (1) the 24h power chart now plots Total drawn / Compressor /
Internal add. heat (kW, with legend) instead of compressor-only; (2) the temp
chart gains an Extract air (BT20) line and BT sensor codes in the legend
(Outdoor BT1 / Supply BT2 / Return BT3), plus a 'supply/return = the heating loop
(in-floor / radiators)' subtitle; (3) a 'data as of <time>' stamp under the card
header showing the latest poll. heat12->heat13.
