chore: backport #22084 (feat: add RPC endpoints to manipulate time) to v4-next

[AztecBot]

Summary

Backport of #22084 to v4-next.

Adds RPC endpoints for manipulating time in test environments (sandbox/local-network), including:

• AztecNodeDebug interface with mineBlock() method gated behind AZTEC_NODE_DEBUG env var
• New warpL2TimeAtLeastBy / warpL2TimeAtLeastTo cheat codes for time manipulation
• Composed e2e test for cheat codes over JSON-RPC boundary

Conflicts resolved

Two files had merge conflicts during cherry-pick:

1. yarn-project/aztec/src/cli/aztec_start_action.ts: Added AztecNodeAdminApiSchema and AztecNodeDebugApiSchema imports + service registrations for local-network mode (v4-next already had AztecNodeAdminApiSchema available but it wasn't imported in the local-network path).

2. yarn-project/end-to-end/src/e2e_contract_updates.test.ts: Removed dead maybeSequencer/sequencer code that referenced undeclared variables, and kept the PR's simplified deploy destructuring pattern.

Commits

1. Cherry-pick with conflict markers (preserves original diff)
2. Conflict resolution (only resolves markers)

Backport of #22084
