feat(search): support quoted phrases in advanced search syntax

[lcomplete]

Summary

• Add splitSearchTokens to LuceneService to correctly tokenize search input, supporting double-quoted phrases (e.g. collection:"my collection")
• Add extractAdvancedSearchKeyword static helper that extracts the value after a separator without splitting on the separator character
• Add formatAdvancedSearchText client utility that auto-wraps values containing spaces in double quotes, used in CollectionList when building the search prefill text
• Add unit tests for both the Java tokenizer and the TypeScript formatter
• Update apple-touch-icon and web manifest references in index.html

Test plan

• Run ./mvnw test -pl huntly-server — LuceneServiceSearchSyntaxTest should pass
• Run yarn test in app/client — searchSyntax.test.ts should pass
• Open a collection whose name contains spaces; verify the search bar pre-fills with the name quoted (e.g. collection:"my collection" )
• Confirm plain single-word collection names still work without quotes

🤖 Augment PR Summary

Summary: This PR adds quoted-phrase support to the advanced search syntax so values containing spaces (e.g. collection names) are tokenized, parsed, and prefilled correctly.

Changes:

• Server: add LuceneService.splitSearchTokens to tokenize queries while preserving double-quoted phrases and unescaping quoted characters.
• Server: add extractAdvancedSearchKeyword to extract the value after the first separator (supports values containing additional :, like URLs).
• Server: update extractCompleteSearch to use the new tokenizer and improve blank-input handling in segmentWords.
• Client: add formatAdvancedSearchValue/formatAdvancedSearchText utilities to auto-quote values with spaces/quotes and escape embedded quotes.
• UI: update CollectionList to prefill collection searches using the formatter (e.g. collection:"My Collection").
• Tests: add JUnit tests for Lucene tokenization/extraction and Jest tests for the client formatter.
• Assets: update PWA icon/manifest references in public/index.html (apple touch icon + site.webmanifest).

With splitSearchTokens preserving whitespace inside quoted phrases, collection: values can now include leading/trailing spaces from inside the quotes, and the later findByNameContainingIgnoreCase(collectionName) lookup may fail to match unexpectedly. Consider normalizing the extracted collection value before querying (e.g., trimming).

Severity: low
