Enabling the MSC4143 experimental feature without configuring any transports makes Synapse serve an empty response on the RTC transports API. Clients treat that response as authoritative and do not fall back to the org.matrix.msc4143.rtc_foci property in the client well-known, breaking Element Call with a MISSING_MATRIX_RTC_TRANSPORT error.
This makes the playbook wire the LiveKit JWT service URL into the new matrix_rtc.transports Synapse setting, matching what continuwuity, tuwunel and the client well-known already advertise.

None of these flags exist in current Synapse:
- msc3266_enabled: MSC3266 support was stabilized in Synapse v1.153.0 and the room summary API is now always enabled
- msc4140_enabled: this was never a Synapse configuration setting in any released version. Delayed events have always been controlled by the `max_event_delay_duration` setting, which the playbook was emitting alongside the flag. The toggle is now named `matrix_synapse_delayed_events_enabled`.
- msc4429_enabled: MSC4429 support has not landed in any released Synapse version, so this flag never had any effect

When no experimental features were enabled (e.g. Matrix RTC and Matrix Authentication Service both disabled), the generated homeserver.yaml contained `experimental_features: null`, which Synapse v1.157.0+ does not tolerate and crashes on startup.
The `experimental_features` configuration is now constructed via a dedicated `matrix_synapse_experimental_features` variable (split into `_default`, `_auto` and `_custom`, as is customary), which always yields a mapping (potentially an empty one).

Introduces the `matrix_synapse_experimental_features_msc4429_enabled`
variable (disabled by default), allowing Synapse to notify clients
using the legacy /sync endpoint of profile changes for other users.

Add support for all server_notices settings documented by Synapse:
- room_avatar_url: optional avatar for the server notices room
- room_topic: optional topic for the server notices room
- auto_join: whether users are auto-joined instead of invited (default: false)

Expose Synapse's `msc4306_enabled` experimental flag as a first-class MDAD
variable and wire it into `homeserver.yaml` alongside the other experimental
feature toggles.
This makes thread-subscriptions support explicit in playbook configuration,
rather than requiring operators to inject the upstream flag via raw
`matrix_synapse_configuration_extension_yaml`.
The variable intentionally controls only the Synapse feature flag. It does not
change the default `thread_subscriptions` worker count, which remains `0` in the
standard presets. Keeping those as separate choices avoids auto-starting an
experimental worker just because the upstream feature toggle is enabled.

Add matrix_synapse_ext_password_provider_ldap_tls_options_ca_certs_file
variable to allow specifying a custom CA certificate file for LDAP TLS
verification. Useful when Synapse is running in a container that does not
trust a private/internal CA by default.
Example usage:
matrix_synapse_ext_password_provider_ldap_tls_options_ca_certs_file: /etc/ssl/certs/my-ca.crt
This works around an issue with Matrix Authentication Service's `syn2mas` sub-command (at version v0.16.0),
which chokes with an error:
> Error: Failed to load Synapse configuration
> Caused by:
> invalid type: found unit, expected struct EnableableSection for key "default.cas_config" in homeserver.yaml YAML file
This issue is likely to be fixed in MAS v0.16.1 or v0.17.0.
