Field pickers:
- Replaced addFieldNamePicker with addTextInput for all field
selectors (charge, load, state, time remaining). The FieldNamePicker
component was silently failing to render in some Grafana versions.
Text inputs are universally supported and let users type the exact
field name from their data source.
Time remaining:
- New 'Enable time remaining' toggle + field name in Field Mapping
- Reads the last value from the configured field (expects minutes)
- Displays as a styled card with clock icon and human-readable
duration (e.g. '2h 15m', '45 min', '< 1 min')
Auto-revert horizontal orientation:
- When orientation is set to horizontal but the panel width is < 300px,
automatically switches to vertical so the battery + side content
still fit. The preference is stored, so it reverts back when the
panel is resized larger.
Icon:
- Replaced generic Grafana scaffold logo with a battery SVG icon
that shows in the visualisation picker and panel header.
