feat: add Delta Pro 3 support to schemas and rest client

[rustyy]

Summary

This PR adds first-class support for the EcoFlow Delta Pro 3 across both workspace packages:

• @ecoflow-api/schemas
• @ecoflow-api/rest-client

It introduces typed property/command schemas, a dedicated DeltaPro3 device implementation, factory integration, and comprehensive Jest coverage.

What’s included

• Added new deltaPro3 schema module in @ecoflow-api/schemas:

  • serialNumber support for MR51* devices (DeltaPro3SerialNumber + guard)
  • getProperties schema (deltaPro3QuotaAllSchema)
  • setCommands schema definitions for Delta Pro 3 commands
  • export wiring via packages/schemas/src/deltaPro3/index.ts and root packages/schemas/src/index.ts

• Added new DeltaPro3 device in @ecoflow-api/rest-client:

  • getProperties parsing via deltaPro3QuotaAllSchema
  • command methods for:
    • beep, AC/DC/device/screen timeout, screen brightness
    • AC output toggles and AC frequency
    • 12V output and X-Boost
    • shutdown, charge/discharge limits, backup reserve level
    • low/high-voltage PV max input
    • max AC charging power and I/O charging power
    • smart generator auto-start + start/stop SOC
    • GFCI, Bluetooth timeout, AC energy-saving mode
    • battery charging/discharging order

• Integrated DeltaPro3 in DeviceFactory and added factory test coverage.

• Added test fixture:

  • deltaPro3Properties for shared property parsing/getter tests.

• Expanded tests:

  • new DeltaPro3.test.ts for command payloads + validation behavior
  • updated shared device tests to include Delta Pro 3
  • updated device factory tests for Delta Pro 3 resolution

• Updated docs metadata:

  • packages/rest-client/README.md now lists Delta Pro 3 as supported

• Added changeset:

  • minor bump for @ecoflow-api/rest-client
  • minor bump for @ecoflow-api/schemas

Release impact

• Type: feat
• Versioning: minor (rest-client, schemas)
• Breaking changes: none
