fix: reduce false positives in award detection

Filter SPARQL query to only return entertainment awards (film, TV,
music, theater) and add a canonical award map to normalize variants
(e.g. all Oscar/Academy Award → "Oscar", all Golden Globe → "Golden
Globe"). Non-entertainment awards (orders, medals, honorary degrees)
are excluded both at SPARQL level and via PHP keyword filter.

Also restart messenger container on cache:clear to avoid stale DI
container errors.
