feat: add RPC endpoints to manipulate time

[benesjan]

Summary

Adds RPC endpoints to the Aztec node admin interface for manipulating time in development/testing environments:

• setNextBlockTimestamp(timestamp) — Sets the L1 timestamp for the next block via evm_setNextBlockTimestamp. Does not mine.
• advanceNextBlockTimestampBy(duration) — Advances the L1 timestamp by the given duration (in seconds). Does not mine.
• mineBlock() — Mines an L1 block, ensures we're in a new L2 slot, and forces the sequencer to produce an L2 block.

These endpoints expose time manipulation capabilities through the node admin RPC, enabling sandbox and test environments to control block timestamps without needing direct L1 access.

Closes F-407

Continues from #22008

Changes

• Added setNextBlockTimestamp, advanceNextBlockTimestampBy, and mineBlock to AztecNodeAdmin interface and schema
• Implemented the methods in AztecNodeService using EthCheatCodes and sequencer triggering
• Added trigger() method to Sequencer and SequencerClient for immediate block production
• Added DateProvider parameter to AztecNodeService constructor for time-aware operations
• Added e2e tests in e2e_cheat_codes.test.ts and schema tests

Test plan

• Unit tests for the new admin API schema methods pass
• E2e tests verify:
  • setNextBlockTimestamp + mineBlock produces a block at the target timestamp
  • advanceNextBlockTimestampBy + mineBlock advances time correctly
  • mineBlock alone produces a new block without explicit timestamp setting
