v1.1.0

Added

• Activity log in the admin tool: a bounded log of the 200 most recent events, shown at
  the bottom of the admin page in a fixed-height, scrollable table (newest first). Logged
  events are membership applications (who applied), the admin's approve/reject decision,
  recipient deletions, and list requests by already-approved members. Entries are stored
  in a new logs table and pruned to the newest 200 on each insert.
• List stats on the main page: below the info card, the current number of entries and the
  date of the last update are shown as a localised line (e.g. "No. of entries: 8. Last
  update: 30.08.2026."). Hidden while the list is empty.
• APP_TIMEZONE setting: timezone used to display stored timestamps (the admin activity
  log and the main-page "last update" date). Any PHP timezone identifier, e.g.
  Europe/Berlin. Timestamps are stored in UTC and converted for display; when unset or
  invalid, the server's default timezone is used.

Changed

• Recipient list emails now list public notes in a separate section below the addresses,
  under a divider, instead of appending them inline after each address. This keeps the
  address block clean so it can be copied straight into an email client. Each note line
  has the form Name (email): note, and only recipients that have a public note appear.
  The CSV attachment is unchanged and still carries the note column.
• formatDate() now honours the timezone carried by a DateTimeInterface argument
  (previously the intl formatter ignored it and used PHP's default timezone), so
  timezone-converted values format on the correct local calendar day. Bare Unix-timestamp
  callers are unaffected.
