type-c-service: Pull PortStatus changes from v0.1

Pull request overview

This PR updates the Type-C/PD status surface area by refactoring PortStatus to carry richer negotiated-contract data (SinkContract/SourceContract) including optional PD-specific details, instead of embedding a few boolean flags directly on PortStatus. The Type-C service is adjusted to consume the new contract shape (notably for sink-ready timeout selection), and tests/mocks/examples are updated to construct the new contract structures. This aligns the codebase with the PortStatus changes pulled from the referenced v0.1 work, and centralizes partner-reported PDO flags behind contract methods.

Changes:

• Introduce SinkContract/SourceContract (+ PdSinkInfo/PdSourceInfo) and update PortStatus to use them.
• Update Type-C service logic to derive power/timeout decisions from contract capability + PD info (epr_capable(), unconstrained_power(), etc.).
• Update unit/integration tests, interface mocks, and std examples to build the new contract structures.

File	Description
type-c-service/tests/unconstrained.rs	Update unconstrained-power test setup to populate SinkContract + PD fixed-data flags.
type-c-service/tests/power.rs	Adjust many test fixtures to use SinkContract/SourceContract wrappers instead of raw PowerCapability.
type-c-service/tests/debug_accessory.rs	Update debug accessory status fixture to use SourceContract::from_capability.
type-c-service/src/service/ucsi.rs	Update UCSI charging-status derivation to read contract.capability.
type-c-service/src/controller/power.rs	Use SinkContract helpers and derive sink-ready timeout selection from epr_capable().
type-c-service/src/controller/max_sink_voltage.rs	Align sink-ready deadline setup with the new EPR-capable detection on the sink contract.
type-c-interface/src/port/pd.rs	Adjust docs referencing removed PortStatus fields (partner PDO info now lives under contracts).
type-c-interface/src/control/pd.rs	Add new contract + PD info structs and update PortStatus fields accordingly.
type-c-interface-mocks/tests/connect_disconnect.rs	Update assertions to validate contract capability + derived flags rather than removed PortStatus booleans.
type-c-interface-mocks/src/port/mod.rs	Update mock plug() to populate the new contract structures and PD fixed-data flags.
examples/std/src/lib/type_c/mock_controller.rs	Update std mock controller to populate contract PD info (including unconstrained flag).

🟡 Changes recommended

The new/modified tests include a timing assertion bug (wrong bounds/constant) and a test-name typo that should be corrected to avoid masking regressions and to keep the suite reliable.

examples/rt685s-evk failure is expected as the tps6699x crate will need to be updated once these changes land.
