Align Song of Solomon book data with verses file naming

Rename book data file and update all references to use "Solomon's Song"
(matching verses-1769.json) instead of "Song of Solomon".

Changes:
- Rename song_of_solomon.json → solomons_song.json
- Update "name" field: "Song of Solomon" → "Solomon's Song"
- Update all verse references to use "Solomon's Song X:Y" format

This ensures the book data name matches the verses file exactly,
eliminating the need for normalization redirects.
