Remove legacy polling wait and add exponential backoff to reconnect

Changes:
- Remove 5-second wait in GetUpdates that was used for long-polling.
  With streaming, WaitForUpdatesAndPush already waits for updates before
  calling GetUpdates, making this redundant. GetGameStatus is deprecated.
- Add exponential backoff to Eagle's stream reconnection logic, starting
  at 1 second and doubling up to 30 seconds max.

-### View Filters (Blocking Full Deproto)
+### View Filters (Partially Complete)
 
-The `ProvinceViewFilter` utility currently works entirely with proto types, blocking full deproto of actions that generate province views:
+The view filter utilities now have Scala overloads for server-side use:
 
-| File | Issue | Needed |
-|------|-------|--------|
-| `ProvinceViewFilter.scala` | Takes proto `Province`/`GameState`, returns proto `ProvinceView` | Scala `ProvinceViewT` model |
-| `GameStateViewFilter.scala` | Uses proto types throughout | Depends on `ProvinceViewT` |

-**Blocked Actions**:
-- `EndBattleAftermathPhaseAction` - uses `ProvinceViewFilter` for `revelationChange`, requires lazy proto conversion
-- `PerformReconResolutionAction` - uses `ProvinceViewFilter` for reconned provinces
-- `GameStateFactionExtensions` - uses `ProvinceViewFilter` for `updatedReconnedProvinces`
+**Unblocked Actions** (PR #4752):
+- `EndBattleAftermathPhaseAction` - can now use `filteredProvinceView(province, scalaGameState)`
+- `PerformReconResolutionAction` - can now use Scala overload
+- `GameStateFactionExtensions` - can now use `updatedReconnedProvinces` with Scala types
 
-**Solution**: Create Scala `ProvinceViewT` (and possibly `ProvinceViewC`) that mirrors the proto `ProvinceView`. Then create a protoless `ProvinceViewFilter` that operates on Scala types. The proto version can delegate to the Scala version + convert, or we maintain both during transition.
+**Remaining Work**:
+- Faction-filtered `filteredProvinceView(Province, GameState, FactionId)` still uses proto types
+- `withdrawnFromProvinceView` still uses proto types
+- These are needed for client-facing views with visibility restrictions
