In content/components/vbus.md around lines 27 and extend to the supported
sensors section (lines 125–128) and supported binary sensors section (lines
175–179), add documentation for the new deltasol_bs_db model: state explicitly
which sensor entities and which binary_sensor entities it exposes; if it has
identical sensors to deltasol_bs_plus, append "deltasol_bs_db" to the same line
in the supported sensors list, otherwise add a new dedicated line listing each
sensor name, unit, and meaning; do the same for binary sensors (either add to
the deltasol_bs_plus binary sensor line or add a new line) so users can see
available configuration options for deltasol_bs_db.

In content/components/vbus.md around line 27, the notes field "DeltaSol BS
Drainb." is an unclear abbreviation; replace "Drainb." with the full term
"Drainback" (or the correct full wording if different) so the entry reads
"DeltaSol BS Drainback." and then scan the file for other similar abbreviations
to standardize them for consistency.
