feat(query-builder): Make date filters more user friendly

[malwilley]

Instead of displaying is -24h, the actual search syntax is abstracted away:

age:-24h -> age is after 24h ago
age:+24h -> age is before 24h ago
age:>=2024-01-01 -> age is on or after 2024-01-01

When selecting an operator with equality ("is", "is on or after", etc), it will automatically switch to an ISO date string. Next step is to make that editable with a date picker component.
