* [MM-24529] Preserve hyphenated compound words in Postgres search

Postgres full-text search stripped every hyphen to a space before
building a to_tsquery, so an unquoted search for "t-shirt" degraded
into a loose "t AND shirt" match instead of the compound-word match
the quoted version already got. Fix is Postgres-only; MySQL is gone
and Elasticsearch/Bleve use a different tokenizer/query mechanism
(verified empirically against a live ES instance - out of scope here).

- Remove "-" from the shared specialSearchChars strip list in
  store.go, and add neutralizeNonWordHyphens (utils.go), which keeps
  a hyphen only when flanked by a letter/digit on both sides,
  neutralizing malformed usage (leading/trailing/standalone/repeated)
  that would otherwise reach to_tsquery as a parse error.
- Wire the new helper into post_store.go's tsquery-building path.
- file_info_store.go keeps the old hyphen-to-space behavior: real
  filenames glue a hyphenated name directly to an extension (e.g.
  "photo-2024.jpg"), which Postgres's parser tokenizes as an opaque
  "host"-type token that a hyphen-preserving compound query can never
  match - verified against Postgres. Re-skip the two FileInfo dash
  acceptance tests with an accurate reason instead of "Not working".
- Re-enable the two previously-skipped Postgres post-search dash
  acceptance tests, and extend them with excluded-term, wildcard, and
  letters-digits-compound cases.

* Revert file_info_layer.go changes

Restore the two FileInfo dash acceptance tests to their original
Skip:true/SkipMessage state, matching master exactly. The underlying
fix (file_info_store.go keeps the old hyphen-to-space behavior since
Postgres tokenizes hyphenated-filename+extension as an opaque token)
is unaffected - this only reverts the test scaffolding tweak.
