After copying a backup from Home Assistant, compare its SHA-256 (via
sha256sum on the server) with a hash of the local file. On mismatch,
delete the local copy and send an error notification; the remote backup
is left in place so the run can be retried. If either checksum cannot
be computed, the run fails rather than reporting an unverified copy as
successful.
- Add VERIFY_CHECKSUM config option (default true; "false" skips the check)
- Make boolean config values case-insensitive (VERIFY_CHECKSUM, NTFY_ENABLED,
DISCORD_ENABLED), so "True" now enables them. Previously only lowercase
"true" did, so NTFY_ENABLED="True" silently left ntfy off
- Bump version to 3.3.0
