ui(precedents): collapsible groups by precedent + Hebrew labels + RTL fixes

After running the dual-mode halacha extractor on a real appeals committee
decision (403-17), the pending-review tab surfaced 351 halachot in a
single flat list — the chair correctly pointed out that this is unusable
without grouping. Three fixes:

1. Group pending halachot by precedent (case_law_id). Each group shows
   the citation, court, date, level and item count; default state is
   collapsed so the chair picks one ruling at a time. Within a group,
   items still sort by confidence ascending so the doubtful ones surface
   first. J/K/A/R/E now scope to currently-expanded groups; toggling
   open auto-focuses the first item.

2. Translate the badges that were leaking English: rule_type values
   (`persuasive`, `interpretive`, `binding`, `application`, `procedural`,
   `obiter`) now render as Hebrew labels, and `confidence X.XX` becomes
   `ביטחון X.XX`. The card header no longer repeats the citation since
   it's already in the group header.

3. Strip Unicode bidi marks (U+200E/F/202A-E/2066-9) from displayed
   citations. Nevo PDFs and the upload form embed these in the
   case_number; they render as zero-width but visually push the text
   away from the right edge of the table cell. Also: hide the empty
   court line under the case name in the list (was rendering as a
   stray em-dash), and use a muted em-dash for empty date/level rather
   than blank/dash inconsistency across columns.
