Add MinInstancePercentage display to Service view for stateless services

[Copilot]

Stateless services expose both MinInstanceCount and MinInstancePercentage for availability guarantees. When upgrades or deactivations get stuck on "EnsureAvailability", only MinInstanceCount was visible in the UI, making it unclear if the percentage constraint was blocking the operation.

Changes

• UI: Added MinInstancePercentage display to the state info component for stateless services only
• Types: Added MinInstancePercentage field to IRawPartition interface
• Tests: Updated e2e tests and fixtures to verify the new field displays correctly for stateless services

Visual Impact

The new field appears below Minimum Instance Count for stateless services only, providing complete visibility into availability constraints. For example, if MinInstanceCount is 1 but MinInstancePercentage is 50% on a 10-node cluster, at least 5 instances must remain available—this is now immediately apparent.

Note: MinInstancePercentage is only applicable to stateless services and is not displayed for self-reconfiguring or stateful services.

<issue_description>Is your feature request related to a problem? Please describe.

Stateless services expose a MinInstanceCount and MinInstancePercentage, which are ways of telling SF what service owner thinks is the min capacity of the service to ensure availability. In Service view we expose Min Count, but not min instance percentage. This would be helpful because sometimes upgrades and tenant jobs get stuck on "EnsureAvailability" of a stateless service, because the deactivate would violate one of the two rules. In the case that it is the percentage blocking, it's not obvious to discover that its that aspect of the service, especially when min count is like 1, but min percentage is higher.

Describe the solution you'd like
Add it to the service view. An even better experience would be if something is stuck on EnsureAvailability on the partition, we can point to and say, "Hey, doing this deactivation would take us below the min instance count/percentage"

no sure if this applies to self reconfiguring service, need to verify first

@copilot MinInstancePercentage only applies to stateless service, please remove it from other instances

Corrected in ed1a8fb. MinInstancePercentage now only displays for Stateless services, removed from SelfReconfiguring services.
