fix(hc): bugs found in self-audit of the new refresh + warmup + templates

Refresh (hc_data_refresh.py):
- CRITICAL: drop optout_ending from REFRESHED_FIELDS -- the refresh never
  computes it, so propagating it blanked the channel CSVs and would starve the
  compliance_bundle segment (whose selector IS optout_ending).
- MAJOR: only rewrite leie_excluded when OIG was actually pulled (guard was
  'not skip_oig OR not skip_sam', so a --skip-oig run blanked all exclusion
  flags). Also write 'Y' (matching the original list builder) not '1'.
- Use 'no_reval_flag' (the original vocabulary) instead of 'not_on_list' when an
  NPI drops off the reval list, and clear reval_due_date too.
- Throttle politeness: move time.sleep(0.05) above the early-continue paths so
  EVERY CMS request is spaced, not just the minority that are on the list.
- Guard blank-NPI rows (leave their status untouched instead of mislabeling).
- Master write preserves any columns beyond HEADER (no silent column drop).

Warmup cron (build_healthcare_campaigns_cron.py):
- Fix the daily-slice split: it summed to less than the budget (dropped ~2/day)
  and could OVERSHOOT on tiny totals (each 'other' floored to >=1). Now uses
  divmod for an even remainder and reclaims rounding onto the lead, so
  sum(per_seg) == total_slice exactly for every input (verified 0,1,2,7,100,300).

Templates: the non-revalidation emails rendered {{ .Subscriber.Attribs.detail }}
(a reval due date) under a 'Practice'/'Status'/'Record' label -- a wrong/
confusing personalization on a live send (esp. OIG, selector 'any'). All four
now show the practice name; 'detail' is retired from rendering (revalidation
uses reval_due_date/days_overdue directly).
