Julian Pawlowski 60e05e0815 refactor(currency)!: rename major/minor to base/subunit currency terminology 
Complete terminology migration from confusing "major/minor" to clearer
"base/subunit" currency naming throughout entire codebase, translations,
documentation, tests, and services.

BREAKING CHANGES:

1. **Service API Parameters Renamed**:
   - `get_chartdata`: `minor_currency` → `subunit_currency`
   - `get_apexcharts_yaml`: Updated service_data references from
     `minor_currency: true` to `subunit_currency: true`
   - All automations/scripts using these parameters MUST be updated

2. **Configuration Option Key Changed**:
   - Config entry option: Display mode setting now uses new terminology
   - Internal key: `currency_display_mode` values remain "base"/"subunit"
   - User-facing labels updated in all 5 languages (de, en, nb, nl, sv)

3. **Sensor Entity Key Renamed**:
   - `current_interval_price_major` → `current_interval_price_base`
   - Entity ID changes: `sensor.tibber_home_current_interval_price_major`
     → `sensor.tibber_home_current_interval_price_base`
   - Energy Dashboard configurations MUST update entity references

4. **Function Signatures Changed**:
   - `format_price_unit_major()` → `format_price_unit_base()`
   - `format_price_unit_minor()` → `format_price_unit_subunit()`
   - `get_price_value()`: Parameter `in_euro` deprecated in favor of
     `config_entry` (backward compatible for now)

5. **Translation Keys Renamed**:
   - All language files: Sensor translation key
     `current_interval_price_major` → `current_interval_price_base`
   - Service parameter descriptions updated in all languages
   - Selector options updated: Display mode dropdown values

Changes by Category:

**Core Code (Python)**:
- const.py: Renamed all format_price_unit_*() functions, updated docstrings
- entity_utils/helpers.py: Updated get_price_value() with config-driven
  conversion and backward-compatible in_euro parameter
- sensor/__init__.py: Added display mode filtering for base currency sensor
- sensor/core.py:
  * Implemented suggested_display_precision property for dynamic decimal places
  * Updated native_unit_of_measurement to use get_display_unit_string()
  * Updated all price conversion calls to use config_entry parameter
- sensor/definitions.py: Renamed entity key and updated all
  suggested_display_precision values (2 decimals for most sensors)
- sensor/calculators/*.py: Updated all price conversion calls (8 calculators)
- sensor/helpers.py: Updated aggregate_price_data() signature with config_entry
- sensor/attributes/future.py: Updated future price attributes conversion

**Services**:
- services/chartdata.py: Renamed parameter minor_currency → subunit_currency
  throughout (53 occurrences), updated metadata calculation
- services/apexcharts.py: Updated service_data references in generated YAML
- services/formatters.py: Renamed parameter use_minor_currency →
  use_subunit_currency in aggregate_hourly_exact() and get_period_data()
- sensor/chart_metadata.py: Updated default parameter name

**Translations (5 Languages)**:
- All /translations/*.json:
  * Added new config step "display_settings" with comprehensive explanations
  * Renamed current_interval_price_major → current_interval_price_base
  * Updated service parameter descriptions (subunit_currency)
  * Added selector.currency_display_mode.options with translated labels
- All /custom_translations/*.json:
  * Renamed sensor description keys
  * Updated chart_metadata usage_tips references

**Documentation**:
- docs/user/docs/actions.md: Updated parameter table and feature list
- docs/user/versioned_docs/version-v0.21.0/actions.md: Backported changes

**Tests**:
- Updated 7 test files with renamed parameters and conversion logic:
  * test_connect_segments.py: Renamed minor/major to subunit/base
  * test_period_data_format.py: Updated period price conversion tests
  * test_avg_none_fallback.py: Fixed tuple unpacking for new return format
  * test_best_price_e2e.py: Added config_entry parameter to all calls
  * test_cache_validity.py: Fixed cache data structure (price_info key)
  * test_coordinator_shutdown.py: Added repair_manager mock
  * test_midnight_turnover.py: Added config_entry parameter
  * test_peak_price_e2e.py: Added config_entry parameter, fixed price_avg → price_mean
  * test_percentage_calculations.py: Added config_entry mock

**Coordinator/Period Calculation**:
- coordinator/periods.py: Added config_entry parameter to
  calculate_periods_with_relaxation() calls (2 locations)

Migration Guide:

1. **Update Service Calls in Automations/Scripts**:
   \`\`\`yaml
   # Before:
   service: tibber_prices.get_chartdata
   data:
     minor_currency: true

   # After:
   service: tibber_prices.get_chartdata
   data:
     subunit_currency: true
   \`\`\`

2. **Update Energy Dashboard Configuration**:
   - Settings → Dashboards → Energy
   - Replace sensor entity:
     `sensor.tibber_home_current_interval_price_major` →
     `sensor.tibber_home_current_interval_price_base`

3. **Review Integration Configuration**:
   - Settings → Devices & Services → Tibber Prices → Configure
   - New "Currency Display Settings" step added
   - Default mode depends on currency (EUR → subunit, Scandinavian → base)

Rationale:

The "major/minor" terminology was confusing and didn't clearly communicate:
- **Major** → Unclear if this means "primary" or "large value"
- **Minor** → Easily confused with "less important" rather than "smaller unit"

New terminology is precise and self-explanatory:
- **Base currency** → Standard ISO currency (€, kr, $, £)
- **Subunit currency** → Fractional unit (ct, øre, ¢, p)

This aligns with:
- International terminology (ISO 4217 standard)
- Banking/financial industry conventions
- User expectations from payment processing systems

Impact: Aligns currency terminology with international standards. Users must
update service calls, automations, and Energy Dashboard configuration after
upgrade.

Website

This website is built using Docusaurus, a modern static website generator.

Installation

yarn

Local Development

yarn start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

yarn build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

USE_SSH=true yarn deploy

Not using SSH:

GIT_USER=<Your GitHub username> yarn deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
