feat(config): add missing env vars to v24.04 from config.sample.php and config.apps.sample.php (#475)

* feat(config): add missing env vars from config.sample.php and config.apps.sample.php

Expose additional ownCloud configuration parameters as OWNCLOUD_* environment
variables, covering options from both config/config.sample.php and
config/config.apps.sample.php that were previously only configurable by
manually editing config.php.

New variables cover: user/auth settings, mail, proxy, trash bin, file
versioning, logging, previews, DAV, sharing, file storage, security,
app management, antivirus, PDF viewer, firstrun wizard client URLs, LDAP,
metrics, Collabora, WOPI/Office Online, workflow retention, and more.

Also hardcodes `web-updater.enabled = false` as Docker installs upgrade
by pulling a new image rather than using the in-app web updater.

* feat(config): add OWNCLOUD_REDIS_TLS_* env vars for Redis TLS connections

Expose the full set of phpredis connection_parameters stream context
options as OWNCLOUD_REDIS_TLS_* env vars, enabling TLS/mTLS connections
to Redis without manually editing config.php.

Single-server: options placed under redis.connection_parameters.stream.*
Cluster:       options placed flat in redis.cluster.connection_parameters.*
(difference follows phpredis/ownCloud upstream structure)

New variables: OWNCLOUD_REDIS_TLS_CAFILE, OWNCLOUD_REDIS_TLS_CAPATH,
OWNCLOUD_REDIS_TLS_LOCAL_CERT, OWNCLOUD_REDIS_TLS_LOCAL_PK,
OWNCLOUD_REDIS_TLS_PASSPHRASE, OWNCLOUD_REDIS_TLS_CIPHERS,
OWNCLOUD_REDIS_TLS_PEER_NAME, OWNCLOUD_REDIS_TLS_VERIFY_PEER,
OWNCLOUD_REDIS_TLS_VERIFY_PEER_NAME, OWNCLOUD_REDIS_TLS_ALLOW_SELF_SIGNED

* feat(config): remove memcache env vars from v24.04

The Docker image does not ship a memcached client library, so the
OWNCLOUD_MEMCACHED_* and OWNCLOUD_MEMCACHE_* env vars are dead config.
Remove the full memcached branch from config.php, the declarations from
20-memcached.sh, 45-caching.sh, and 85-others.sh, and the entries from
ENVIRONMENT.md.

* feat(config): restore OWNCLOUD_MEMCACHE_LOCAL env var

OWNCLOUD_MEMCACHE_LOCAL controls the local memory cache backend (APCu by
default) which is unrelated to the memcached service — it was incorrectly
removed together with the memcached-specific vars.
