SearchIndex: fix TypeError when $QUERY global is null

QueryParser::convert() requires a string argument, but the global
$QUERY can be null. Coalesce to empty string to match prior behavior.

SearchIndex: rewrite FulltextSearch to use FrequencyCollectionSearch

Replace FulltextIndex->lookupWords() with FrequencyCollectionSearch which
correctly handles the compact tuple format written by the new Indexer.

Introduce QueryEvaluator with typed stack entries (PageSet,
NamespacePredicate, NegatedEntry) for RPN query evaluation. NOT wraps
its operand instead of computing a universe complement, so AND with a
negated operand becomes efficient set subtraction. The full page index
is only loaded for standalone negative or namespace-only queries.

Move QueryParser and QueryEvaluator into the new Search\Query namespace
along with the stack entry types.

Simplify FulltextSearch to orchestration: parse query, look up words,
evaluate, filter, sort. Replace FT_SNIPPET_NUMBER constant with
maxSnippets property. Combine ACL/existence/time filtering into a
single pass.

This makes sure all files use line lenghts shorter than 120 characters.

This is a quick fix. It might not always be the nicest change.

feat: improve search as a primary means to create new pages

Specifically, this pull request checks if the current query is already a
valid pageid and then return that as suggested pageid.

Also, tests are added for this method.

Fixes #2355

PS: We may want to somehow better educate/nudge users to use the better
way of creating pages by creating links on existing pages.
