[FLI-919] Context based command bar

[markphelps]

Problem

Now that we have a command bar in v1.39: https://twitter.com/flipt_io/status/1772254008809251019, it would be neat if it took into account the current section in the application that you are on.

Ideal Solution

If im on the /flags page, and I open the command bar it should allow me to quickly jump to New Flag, same for segments

If I'm on a specific flag page like /flags/example, and I hit the command bar, it should allow me to quickly create a new variant or rule (variant flag type), or rollout (boolean flag type)

Similiar for segment -> constraint

Additional actions like Copy To Namespace should be able to be performed quickly by opening the command bar on a single flag or segment page in the UI

Theres likely more we can do, but these seem like good first steps

Additional Context

This is the library we use for command bar: https://github.com/pacocoursey/cmdk

Here is where its implemented in Flipt UI: https://github.com/flipt-io/flipt/blob/main/ui/src/components/command/CommandDialog.tsx
