fix: don't link hyphen-only numeric ranges as verse references

[mahmoodhamdi]

Summary

Closes: #3267

The verse-reference regex used by formatVerseReferencesToLinks (called from
FootnoteText) accepted either : or - as the chapter:verse separator. As
a result, an isolated range like (7-10) inside a translation footnote was
rewritten to /7-10 and routed to Surah 7 — even when the surrounding text
referenced a different Surah (the original report was Hindi Surah Al-Mulk 67:5
referencing As-Saffat 37:7-10).

Tightens the regex to require : between chapter and verse so only
conventional references become links: 1:1, 1:1-3, 1:1-2:3. Bare
hyphen-separated numbers are left as plain text.

Type of Change

• 🐛 Bug fix (non-breaking change which fixes an issue)

Scope Confirmation

• This PR addresses one feature/fix only

Test Plan

• Updated the existing "partial verse references" test to expect no link
  for 1-1.
• Added a regression test for the reported case
  (See Surah As-Saffat, verses (7-10) for context).
• yarn test — 935 / 935 tests pass.
• yarn lint on the two changed files — clean.

Manual reproduction (before fix):

1. Open Surah Al-Mulk 67:5 with the Hindi translation by Maulana Azizul Haque al-Umari enabled.
2. Open the footnote for the word "शैतानों".
3. Click the (7-10) hyperlink — currently routes to /7-10 (Surah 7).

After the fix, the (7-10) text remains plain (not linked), so the footnote
no longer misroutes.

Rollback Safety

• Can be safely reverted without data issues or migrations
