Fix SVG markup in select options, add missing name placeholders

Remove SVG icon function calls from <option> textContent — native
select elements render markup as literal text. Capture template options
now show "name (engine_type)", source options show just the name.

Add i18n placeholders to automation and scene editor name inputs.
Rename HAOS Scenes device from "{server_name} Scenes" to "Scenes".
