Add generic ioBroker vehicle template

[andig]

Adds a generic iobroker vehicle template, modeled after the existing ioBroker charger and meter templates (rest-api adapter, basic auth, URL-encoded datapoint ids). Any ioBroker adapter that exposes vehicle data can now be used, not just ioBroker.bmw.

Feature set is on par with the generic Home Assistant vehicle:

Home Assistant	ioBroker
soc, range, status, statusA/B/C, limitSoc, odometer, climater, finishTime	same param names
start_charging / stop_charging	chargeEnable (single writable datapoint)
wakeup, setMaxCurrent	same

statusA/B/C accept comma-separated datapoint values and compile into a jq mapping to A/B/C. If none are given the raw value is passed through, so a datapoint that already yields A/B/C works without further configuration.

The BMW-specific ioBroker.bmw template is marked deprecated: true. Existing configurations keep resolving via ByName, it is only hidden from new configurations.

**issue (bug_risk):** The template enables Basic authentication when `.user` is set, even if `.password` is absent. This contradicts the template's documented behavior that no password means no authentication and sends requests with an empty password instead of unauthenticated requests.

**Triggers:** When a configuration supplies `user` without `password`.

**Suggested fix:** Gate the `auth` blocks on `.password` (or on both `.user` and `.password`) so missing credentials do not enable Basic authentication.

**issue (review_instructions):** Use consistent capitalization for the technical term `URI`.

Please change `uri` to `URI` here, matching the capitalization used for this acronym elsewhere in the template documentation and parameter terminology.

**issue (review_instructions):** Correct the German article for `URI`.

`URI` is conventionally feminine in German; use `Die vollständige URI der ioBroker-Instanz` (including the hyphenated compound) for consistent, idiomatic wording.

Sourcery assessment

Needs a human reviewer. 1 finding to address first, and the template adds HTTP write operations that can start or stop charging, change the charging current, or wake a vehicle through configured ioBroker datapoints. If the mapping or value handling is wrong, a command can take effect before the change is reverted, leaving an external vehicle action and associated energy or access impact that reverting cannot undo.

Actually this is not possible to request. We have to change following topic:

See also discription of this Adapter: https://github.com/ioBroker/ioBroker.rest-api#usage

At the same time, we should also change the port from 8082 to the generic 8093. This will work for more people plug & play.
