fix(identity-service): resolve @ts-ignore suppressions at Credo-ts framework boundary

[cynox-66]

Summary

Resolves the remaining @ts-ignore suppressions in core heka-identity-service files by replacing them with typed assertions, runtime validation, and proper ambient type declarations.

This continues the type-safety cleanup started in #127 and focuses on the remaining framework/library boundary cases that required deeper fixes rather than direct @ts-expect-error replacements.

Changes

1. AnonCreds registry runtime validation

• Added a runtime guard ensuring at least one AnonCreds-capable DID method is configured
• Replaced @ts-ignore with a narrowed tuple assertion:
  as [AnonCredsRegistry, ...AnonCredsRegistry[]]
• Preserves Credo-ts type guarantees while keeping the configuration-driven registry setup

2. Typed AnonCreds proof access

• Replaced @ts-ignore in proof.service.ts
• Added explicit AnonCredsProof narrowing for requested_proof.revealed_attrs access

3. Dead field cleanup

• Removed the unused tenantId field and corresponding suppression in did-registrar.service.ts
• Preserved existing bootstrap behavior by keeping initTenant() execution intact

4. Ambient declarations for @digitalcredentials/bitstring

• Added local .d.ts declarations for the untyped dependency
• Removed related @ts-ignore and ESLint suppression boilerplate

Notes

The AnonCreds registry validation now fails fast when no AnonCreds-capable DID method is configured (for example DID_METHODS=key).

Previously this configuration would silently create a broken agent and fail later during credential operations. The new behavior surfaces the configuration issue immediately at startup with a clear error message.

Result

• Removes the remaining framework-boundary @ts-ignore suppressions in heka-identity-service
• Improves runtime safety for invalid DID method configurations
• Preserves existing runtime behavior for valid deployments
• Keeps Credo-ts integration points fully typed

• Chores
  • Enhanced TypeScript configuration for development environment setup and improved type definitions for project dependencies.

[cynox-66]

Tracked down the CI failure , the ambient declaration file was included in tsconfig.src.json but not in tsconfig.test.json, so the test typecheck couldn't resolve the module declaration during transitive imports.

Added the .d.ts include to the test config and re-ran the full typecheck/lint flow locally ...

[cynox-66]

Pushed a follow-up fix for the failing typecheck related to the local @digitalcredentials/bitstring declarations.

The issue ended up being that the new .d.ts file wasn’t included in the test typecheck config, even though the source typecheck passed locally. I updated the tsconfig include patterns and re-ran the validation flow locally (check-types, lint, build, and unit tests).

Also cleaned up the ESLint issues in the declaration file while rechecking the CI flow.

Still learning some of the repo/CI edge cases here, so thanks for the patience while I worked through it carefully.

📝 Walkthrough

Walkthrough

This PR improves TypeScript type safety by introducing type declarations for the @digitalcredentials/bitstring dependency, removes or upgrades suppression comments that masked missing types, refactors DidRegistrarService to not store tenant id, and expands test file patterns in TypeScript configuration.

Changes

TypeScript Type Definitions and Service Refactoring

Layer / File(s)	Summary
Bitstring type definitions and status-list cleanup heka-identity-service/src/types/digitalcredentials-bitstring.d.ts, heka-identity-service/src/revocation/status-list/status-list.service.ts	New ambient type declarations for @digitalcredentials/bitstring module define Bitstring class (constructor accepting { length: number } or { buffer: Uint8Array }, instance methods set/get/encodeBits, static decodeBits), enabling removal of ESLint and @ts-expect-error suppressions from status-list.service.ts.
TypeScript error suppression updates in service modules heka-identity-service/src/common/agent/agent-modules.provider.ts, heka-identity-service/src/proof/proof.service.ts	Agent modules provider replaces @ts-ignore with @ts-expect-error for AnonCredsModule registries field and documents tuple type expectation vs. runtime-conditional population; proof service removes @ts-ignore suppression from revealed_attrs access while keeping logic unchanged.
DidRegistrarService tenant initialization refactoring heka-identity-service/src/common/did-registrar/did-registrar.service.ts	Removes class-level tenantId field and updates onApplicationBootstrap to call initTenant() for side effects only without storing the returned tenant id; comments document the record is reserved for future DID creation flow changes.
Test TypeScript configuration expansion heka-identity-service/tsconfig.test.json	Expands include globs to add src/**/*.test.ts and src/**/*.spec.ts patterns for broader test TypeScript project coverage.

🐰 Types declared with care and grace,
Suppressions swept from every place,
Bitstring bundled, warnings gone,
