HOLI-9524: use index and fix distance calculation

See merge request app/holi-app-volunteering!41

This commit extends the `Engagement` type by three new fields that are set if used in a
recommendation query response:

* `matchedTopics`
* `matchedSkills`
* `matchedGeoLocationDistanceInMeters`

The first two fields contain topics and skills that a recommendation query asked for if (and only
if) those were the reason for the recommendation to include a given engagement in the response.
A match will only be included if it surpasses a certain threshold (set to 0.5 in this commit).

If `geoLocationId` is passed as a query parameter`matchedGeoLocationDistanceInMeters` contains the
distance in meters from the geolocation resolved from `geoLocationId`to the geolocation of the
engagement opportunity.

* query now (implicitly) uses the HNSW index on embedding_array
* query now uses the `<#>` operator to sort by distance which can (and will) take advantage of the
  index for the newly introduced `location_gps` column which combines (`longitude`,`latitude`) into
  a PostGIS geometry
* distance calculation is fixed - it calculated before with two different units (distance in
  "angle" (RSID 4326) vs. distance in meters (RSID 3857, Pseudo-Mercator plane projection))
