Port QEPro to ophyd-async and extract plans

[Thomas Hopkins (thopkins32)]

Assisted-by: oh-my-pi:gpt-5.6-terra

Summary

• Replaced the classic Ophyd QEPro driver with an ophyd-async QEPro / QEProTEC implementation using declarative EPICS signals.
• Preserved the QEPro PV contract, raw feature-bit API, async TEC setpoint completion, and acquisition completion on the COLLECT_RBV falling edge.
• Added deterministic QEProMock behavior for local tests, including completed collection cycles without wall-clock sleeps.
• Kept QEPro as a one-shot StandardReadable with structural trigger() semantics:
  • trigger returns immediately with an AsyncStatus
  • the status completes after acquisition finishes
  • the nine legacy event fields are freshly read after each completed trigger
  • no StandardDetector / fly / asset-provider lifecycle was introduced
• Restricted normal event output to the legacy QEPro fields: x_axis, output, sample, dark, reference, spectrum_type, integration_time, num_spectra, and buff_capacity.
• Added reusable QEPro-only plan primitives: configure_qepro, take_qepro_dark_frame, take_qepro_reference_frame, and set_qepro_temperature.
• Expanded behavioral coverage for PV mapping, feature masks, trigger/TEC status boundaries, event/config field
  surfaces, frame restoration, and fresh post-trigger spectrum reads.

Motivation / Context

Will be helpful for testing acquisition workflows offline for the Blop optimization described in #14

What changed in this PR

Ports QEPro support to ophyd-async and adds reusable Bluesky configuration and acquisition plans.

Changes:

• Adds asynchronous QEPro/TEC devices with deterministic mock behavior.
• Adds QEPro configuration, frame-capture, and temperature plans.
• Adds behavioral tests and removes the obsolete PyEPICS development dependency.

🔵 Needs a closer look

EDC cannot be disabled through the configuration plan, and the lockfile conflicts with the declared development dependencies.

🔵 Needs a closer look

Hardware-facing EPICS acquisition and TEC lifecycle behavior warrants final human review despite comprehensive mock coverage.
