Update D4A Configuration (#4166)

* Update D4A Configuration

D4A had some breaking config changes so this commit fixes them and gets us back into compliance with upstream. And since we run in a docker container we can use the /data/storage default.

* Update D4A Configuration to harmonise with bot mode

Change the default config for D4A to align with bot mode default in mdad. This should also avert a bit of a mess of a potential bug.

* Change D4A Room State Backing Store variable name and fix SPDX Headers

* Align D4A config with new schema

* Fix D4A Config Lint Error

* Update D4A SPDX Entries

* Do not use double quotes around `to_json` values

+# Safe mode provides recovery options for some failure modes when Draupnir
+# fails to start. For example, if the bot fails to resolve a room alias in
+# a watched list, or if the server has parted from a protected room and can't
+# find a way back in. Safe mode will provide different options to recover from
+# these. Such as unprotecting the room or unwatching the policy list.
+# By default Draupnir will boot into safe mode only when the failure mode
+# is recoverable.
+# It may be desirable to prevent the bot from starting into safe mode if you have
+# a pager system when Draupnir is down, as Draupnir could prevent your monitoring
+# system from identifying a failure to start.
+#safeMode:
+#  # The option for entering safe mode when Draupnir fails to start up.
+#  # - "RecoveryOnly" will only start the bot in safe mode when there are recovery options available. This is the default.
+#  # - "Never" will never start the bot in safe mode when Draupnir fails to start normally.
+#  # - "Always" will always start the bot in safe mode when Draupnir fails to start normally.
