chore: remove unused endpoints and dead code paths

[hankbobtheresearchoor]

Summary

Removes three HTTP endpoints that are not consumed by any client — Swift provider, console UI, or external integrations — along with their exclusive callee functions.

Changes

1. GET /v1/provider/node-earnings — per-node earnings history

• Removes handleNodeEarnings handler (billing_handlers.go)
• Removes GetProviderEarnings() and GetProviderEarningsSummary() from store interface and both Postgres/Memory implementations
• Rewires integration tests to use GetAccountEarnings() (account-scoped) instead of GetProviderEarnings() (node-scoped)
• Removes TestNodeEarningsUsesLifetimeTotalsInsteadOfLimitedSlice test
• Removes TestProviderEarnings_GetByProviderKey and TestProviderEarnings_NewestFirst store tests; renames TestProviderEarnings_LimitRespected → TestProviderEarnings_LimitForAccount

2. GET /v1/billing/wallet/balance — wallet balance lookup

• Removes handleWalletBalance handler (billing_handlers.go)
• billing.Ledger().Balance() is preserved — still used by other endpoints (stripe_payouts.go, consumer.go)

3. GET /v1/runtime/manifest — runtime hash inspection

• Removes handleRuntimeManifest handler (server.go) and route registration
• Removes runtime_manifest:v1 cache invalidation from release_handlers.go
• Runtime manifest infrastructure (SyncRuntimeManifest, SetRuntimeManifest, knownRuntimeManifest) kept intact — still in active use for provider runtime verification on registration and challenge revalidation
• Removes now-unused encoding/json import from server.go

@hankbobtheresearchoor is attempting to deploy a commit to the EigenLabs Team on Vercel.

A member of the Team first needs to authorize it.

I'll take a look at this.

Review Summary

Clean removal PR — all three endpoints, their handlers, route registrations, and store methods are consistently removed. Build + tests pass.

Two minor cleanup items (see inline):

• 🟡 Orphaned nodeEarningsResponse struct in test file
• 🟡 Indentation drift in integration test

Vercel failures are the Authorization required pattern (not a code defect).

[hankbobtheresearchoor]

🟡 Indentation drifted — these lines have an extra tab compared to the surrounding function body. The // Step 8 comment at line 970 is at the correct level, but lines 971-983 are double-indented. Also expectedPayout{ at line 983 is missing a space before the brace (expectedPayout {).

[hankbobtheresearchoor]

🟡 Orphaned type: nodeEarningsResponse at billing_earnings_test.go:26 is unused now — the only test that referenced it was removed. Consider removing the struct definition.

[hankbobtheresearchoor]

Done. 51e8a79: fixed indentation drift in billing_integration_test.go Step 8 block plus missing space before brace, and removed orphaned nodeEarningsResponse struct. All tests pass.

@hankbobtheresearchoor Coordinator CI tests failing, please fix and rebase

[hankbobtheresearchoor]

On it — checking the CI failures and will fix + rebase.

[hankbobtheresearchoor]

Fixed gofmt in billing_earnings_test.go. Commit: 67ab3b6. Tests pass. Force-push blocked for rebase — branch is BEHIND but MERGEABLE.
