WIP Updating the alarm log message POJOs based on #3304

[shroffk]

work in progress... trying to fix #3304

[tynanford]

Thanks. It seems a bit wrong that "enabled" now will be returning a string for the logger API and clients have to know what the date string means. But it nicely allows for the client to show the disable until info in the log table and is a good fix for now.

It's getting late and might be doing something silly. Will re-visit tomorrow

... but right now it seems like the "enabled" field is missing from the API results with this patch. So en is always null

Before:

severity	"OK"
message	"Disabled"
value	""
time	"2025-03-06T09:08:37.805Z"
current_severity	"OK"
current_message	"OK"
message_time	"2025-03-06T09:08:37.805Z"
config	"state:/Accelerator/Test/Accelerator:Alarm:BoolInvalid"
pv	"Accelerator:Alarm:BoolInvalid"
enabled	false

With this change:

severity	"OK"
message	"Disabled"
value	""
time	"2025-03-06T09:08:37.805Z"
current_severity	"OK"
current_message	"OK"
message_time	"2025-03-06T09:08:37.805Z"
config	"state:/Accelerator/Test/Accelerator:Alarm:BoolInvalid"
pv	"Accelerator:Alarm:BoolInvalid"
