zabbix7-proxy: Expose ProxyBufferMode and ProxyMemoryBufferSize in GUI

[patrickstump]

Feature Request

The os-zabbix7-proxy plugin (v1.16) does not expose the Zabbix 7.0 proxy
memory buffer parameters in the GUI settings.

Missing Parameters

Parameter	Type	Range	Description
ProxyBufferMode	enum	disk, memory, hybrid	Data buffering strategy (new in 7.0)
ProxyMemoryBufferSize	size	128K–2G	Shared memory segment size
ProxyMemoryBufferAge	integer	0, 600–864000 sec	Max age before flush to disk

Why This Matters

These are the most significant performance parameters added to the Zabbix
proxy in 7.0. The shared memory buffer (ProxyBufferMode=hybrid) replaces
the SQLite-only data path from 6.0, dramatically improving throughput.
Without GUI exposure, these must be manually appended to zabbix_proxy.conf
— and any GUI save regenerates the config, removing manual additions.

Other options missing in 7.0 or 7.4?

keep in mind the plugin is version agnostic so you can add optional new settings but they won't work in the older versions still supported

saw that... Cool.
Also, 7.2 has to go (EOL) and in a couple months 7.4 is becoming EOL. So your dream of only LTS could become a reality

interesting... until Zabbix 8.2 Q1 2027 at least :)

want to make a PR in plugins and tools to remove 7.2?
