103 quantum registers

[Iliasmi]

Summary

This PR adds explicit quantum and classical register support across the circuit model, backend API, circuit editor, simulator, and results view.

• Added register management for quantum and classical registers, including creating/deleting registers and adding/removing qubits or classical bits.
• Introduced a shared RegisterType discriminator and extended circuit DTOs/API requests to handle classical registers and measurement destinations.
• Updated measurement handling so measurement gates must target exactly one qubit, cannot be inverted or controlled, and must write to at least one classical bit.
• Added UI flows for managing registers and selecting a classical bit when placing measurement gates.
• Reworked circuit rendering to display quantum and classical register sections, including collapsible classical registers and separate classical wire styling.
• Improved drag/drop and scheduling logic so operations are placed only on valid quantum rows and collisions are handled consistently.
• Reworked simulation execution to support single-qubit and mid-circuit measurements, classical memory/readout, measurement mappings, shot-based outcomes, and optional final readout of unmeasured qubits.
• Updated the results view to show measurement/readout histograms, outcome tables, measurement mappings, endianness/order controls, filters, and large-circuit warnings.
• Added and updated backend/frontend tests around registers, measurements, simulation translation, chart data, and results rendering.
• Adjusted build/dev setup so Gradle uses a project-local Node/npm for Spotless and updated the README Docker Compose command.
