Index PDF and Office file contents via Apache Tika

Solr 10 dropped the ExtractingRequestHandler, so a dedicated Tika
container on the Solr VPS (Caddy route /tika/*, own basic-auth
credential; Tika itself has no auth) extracts file text during
indexing: TikaDownloadContentIndexer listens on
BeforeDocumentIsProcessedForIndexingEvent, resolves the file through
the existing DownloadFileResolver and appends the text (mime
whitelist, 30 MB cap, 100k chars, fail-soft) to the document's content
field. Extractions are cached in var/tika-cache keyed on
path+size+mtime - a full re-index of 177 downloads drops from 2:12 min
to 27 s, replacing a file re-extracts naturally. Datasheet
specifications ("625i", "genlock") are now searchable. Spec v1.15.
