Stateful history delta implementation changes + testing

[WhitWaldo]

Description

Performs a series of changes to the implementation in #1862:

• Removes the [RequiresDaprHeadFactAttribute] as this functionality is already performed by [MinimumDaprRuntimeFact]
• Replaced scan-based eviction for dictionary + linked-list LRU (yielding O(1))
• Throws on invalid instance/byte limits and negative TTL values (0 and null supported)
• Added more testing:
  • Using actual work-item streams, prove that even if it finishes late, the old stream handler cannot override the current stream's cached history
  • Old tests only validated event counts, new tests assert exact event IDs and checks order of each operation
  • Validated more completion actions: specifically Completed, Failed, Terminated, and ContinuedAsNew proving correct operation
  • Confirms correct use of GetInstanceHistoryAsync and with exactly one history request
  • Cache behavior was only tested sequentially, now proves concurrent execution with Put, Get, Remov, accounting, eviction bounds, and Reset, verifying that count/byte limits remain valid and retired-generation writes cannot repopulate the cache
  • Validates one-entry cache and coordinates two workflows so at least one history is evicted before its next turn. Verifies both complete correctly, receive deltas, and that the worker performs at least one real GetInstanceHistory recovery.

Merging although it's possible this will require another fix PR prior to 1.19 - cannot validate as there's no RC for 1.19 yet.
