Fix subscription expiry logic and HTML entities in page titles

Subscription expiry (SubscriptionExpiryBackgroundService):
- Trials with no grace period now go directly Active -> Expired instead
  of briefly entering GracePeriod for a day, which was causing repeated
  'Grace Period Started' admin notification emails
- Remove redundant isTrial variable (query already filters to non-Stripe
  companies, so all processed companies are trials by definition)
- Save per-company inside the loop so a single SaveChangesAsync failure
  no longer discards all other companies' status changes and notification
  log entries (which was the other cause of repeated emails)

HTML entities in page titles (33 views):
- Replace – / — with plain ' - ' in ViewData["Title"] C#
  strings; Razor HTML-encodes these when rendering @ViewData["Title"],
  causing browsers to display the literal text '–' instead of a dash
