feat(license): nouveau search migration for licenses endpoint

[rudra-superrr]

Description: Migrates the /api/licenses endpoint from the legacy CouchDB view-based search to CouchDB Nouveau (Lucene-backed) search, adding proper server-side pagination and sort support.

Files Changed

File	Change
LicenseSearchHandler.java	New Nouveau license search handler. Defines license index schema and sort mapping, adds OR-based quick search by fullname/id/shortname, and adds searchWithPagination with match-all query for blank search text.
LicenseSearchHandlerTest.java	Unit test file for license Nouveau search behavior. Covers sort-column mapping plus the new pagination branch contract: blank search maps to match-all and non-blank search is trimmed.
LicenseDatabaseHandler.java	Removed LicenseSearchHandler dependency and removed DB-layer search/pagination orchestration methods. Keeps DB/repository responsibilities; exposes convertToLicenseSummary for handler-level orchestration.
LicenseHandler.java	Now owns LicenseSearchHandler and routes searchLicenseWithPagination through it, then converts results to license summaries. Removes legacy non-paginated searchLicense path.
licenses.thrift	Contains LicenseSortColumn enum and paginated searchLicenseWithPagination method. Legacy non-paginated searchLicense method removed.
NouveauLuceneAwareDatabaseConnector.java	addDesignDoc updated so a newly introduced index key is persisted into an existing design doc instead of being skipped. This is a shared Nouveau infrastructure fix, not license-only logic.
Sw360LicenseService.java	Provides getLicensesWithPagination and paginated searchLicenses(searchText, pageable). pageableToPaginationData aligned to ProjectService style and maps sort properties including licenseType and score.
LicenseController.java	Listing endpoint routes blank search to paginated list API and non-blank search to paginated quick-search API; OpenAPI tag text documents supported sort columns for paginated endpoints.
