Related verses (#385)

• feat: semantic related verses (parallel to vocabulary flow)

Adds SemanticRelatedVersesService backed by an in-memory NRSV-keyed lookup over a 36 MB JSON resource shipped in step-core-data. Surfaced via a new relatedrefsSemantic search token routed through the existing masterSearch pipeline so URL share / bookmark / reload / column-link all work for free; SearchResult.searchType is normalized back to RELATED_VERSES on the wire so the existing frontend rendering case matches without a new switch arm.

Backend:

• SemanticRelatedVersesService (interface) + impl: streaming Jackson parser with a local interner; eager singleton bound in StepCoreModule; pure NRSV-in / NRSV-out, no JSword dependency.
• SearchServiceImpl: new field + ctor param; new dispatch in enhanceSearchTokens, runCorrectSearch, executeOneSearch; new runSemanticRelatedVerses executor handles user-v11n -> NRSV inbound and NRSV -> user-v11n outbound mapping verse-by-verse with DefaultKeyList to preserve ranking; reuses JSwordSearchService#getResultsFromTrimmedKeys (avoids rankAndTrimResults so order survives); top-50 cap, OSIS dedup.
• SearchType.RELATED_VERSES_SEMANTIC (internal); normalization wrapper on getBestSearchType maps it back to RELATED_VERSES for the frontend.
• SearchToken.RELATED_VERSES_SEMANTIC = "relatedrefsSemantic".
• ValidateUtils XSS branch extended to accept the new token.
• SearchServiceImplTest constructor call patched (extra null param).

Frontend:

• step.util.js verse popup template restructured: new .relatedVersesChooser row above the vocab table with vocabulary | semantics anchors; .relatedVerses removed from the bottom .verseVocabLinks div; new click handler navigates via relatedrefsSemantic token; new getSource and renderEnhancedToken cases produce a distinct "Sem:" pill.
• view_main_search.js: three sibling fall-through cases added next to RELATED_VERSES.
• step_constants.js: RELATED_VERSES_SEMANTIC constant.
• verse_popup.scss: .relatedVersesChooser block (mirror of .verseVocabLinks divider, dotted bottom border).

i18n: 5 new keys in InteractiveBundle.properties only (English base); locale bundles intentionally untouched per upstream sync policy.

Data: bible_semantic_export_minified.json (NRSV-keyed; 31,087 keys x 100 ranked refs each) staged under step-core-data/.../related-verses/.

• fix(verse_popup): drop margin/padding on .relatedVersesChooser anchors

The 10px margin-right + 10px padding-right was copy-pasted from .verseVocabLinks where it brackets a CSS border-right divider; the chooser uses a literal "|" character instead, so the same rule just adds dead space and extends the underline 10px past "vocabulary". Removing the nested anchor block lets the popup-wide a { padding: 0px } rule apply.

• fix(search): honor display mode for semantic related verses

Pass the user's full version stack to getResultsFromTrimmedKeys so COLUMN / INTERLINEAR / INTERLEAVED / COMPARE modes survive past getBestInterlinearMode's empty-extras short-circuit. Inlined NRSV-rank ordering via DefaultKeyList is preserved.

• feat(verse_popup): move "See related subjects" into chooser row; drop empty vocab-links box

Inline the three chooser anchors as English literals ("meaning | vocabulary | topics") and add a third .relatedSubjects anchor that previously lived in the bottom .verseVocabLinks row. Delete the five locally-introduced i18n keys (display_verses_related_by, related_by_vocabulary, related_by_semantics, verse_related_semantic, semantic_related_prefix) from InteractiveBundle.properties. Reuse the upstream __s.related_prefix in the semantic-chip body so its rendering matches the vocabulary/topics chips; rename the semantic chip's hover tooltip to "Related verses (meaning)".

Also prune the now-often-empty .verseVocabLinks dotted box: when the verse has no translation tip and was not reached via search, the box would otherwise render with no anchors. Because templatedTable is a jQuery collection of three sibling top-level elements (not a single container), the prune must filter the element out of the collection itself — calling .remove() on a detached top-level element does not prevent qtip from re-attaching it via content.text:templatedTable.

• refactor(search): route semantic related verses through shared Passage pipeline

Rewrite runSemanticRelatedVerses to mirror runRelatedVerses (lexical flow): build an NRSV Passage from the full ranked list, map to the user's versification with VersificationsMapper.map, and hand to buildCombinedVerseBasedResults. Drops the 50-verse cap, the manual DefaultKeyList/HashSet accumulator, per-ref it.next()-only mapping, the local countOnly branch, and the hand-rolled getResultsFromTrimmedKeys call (display-mode fix from 8780d60 now comes for free via the shared helper). Results are canonical-ordered and dedup'd by RangedPassage semantics; 1->N cross-v11n mappings (e.g. Psalm titling) are now kept.
