Add Status Indicators to Hajimari Apps

[h3mmy]

Overview

CURRENTLY INCOMPLETE

Addresses #20 to add Status Indicators to Hajimari Apps

Previous PR #35 is the initial attempt to do so.

Example screenshot:

Notable Changes

• Move from v1beta1.Ingress to v1.Ingress. No adjustments required. Effectively drop-in.
• Uses DiscoveryV1 and EndpointSlices to collect replica statuses instead of the AppsV1 Api as done in Add status indicators to hajimari apps #35. This means we don't have to distinguish between Deployments/DaemonSets/StatefulSets/etc.
• EPSlices are filtered to limit service statuses to those specified in the Ingress.
• Uses Svelte instead of the previous front-end implementation. This makes adjustments consistent with the v0.3.0 milestone.
• Adds a ReplicaInfo field to the models.App object.
• Changes models.AppGroup to use Name instead of Group for label. It makes it less ambiguous when figuring out what's what in the front-end.

Remaining To-dos before PR will exit "Draft" status

• Finish Indicator styling to reflect App Status.
• Automated Tests I can offer to do it but I feel like the structure is still being changed so I'll defer to the codeowner to decide if I should add these
• Adjustments to dev setup? Will do in separate PR.

To finish PR

• Any further changes requested by codeowner(s)

No Problem! I finished up the basic pieces. Let me know if I should add any automated tests. I know the structure is evolving so it makes more sense for me to add those to parts on request so I don't spend time on those unnecessarily.

After some experimenting I decided to use the accent color to indicate live replicas and tune to currentcolor for unavailable replicas. It should be pretty straighforward to adjust these as it's just a linear gradient with hard stops.
