hardware: remove legacy model validation classification

[mksolutionsuniversal]

Summary

Remove the obsolete per-model validation-classification layer from the current BCPC product path.

SupportedIntelMac is now determined directly from detected Apple hardware plus an Intel CPU. Exact Mac model identity remains hardware/reporting context and may still be used where there is a specific compatibility or research reason, but it does not grant normal processor-profile or fan-write permission.

Product behavior

• Any detected Apple + Intel system resolves to SupportedIntelMac without a model whitelist.
• Gaming Optimised remains the global 95% / 95% + Boost Disabled processor policy for SupportedIntelMac.
• Fan writes remain independently gated by the live AppleSMC capability fingerprint and all existing safety/ownership/recovery checks.
• Overview removes the legacy Model validation row.
• Supported Intel Macs show only Platform support in Compatibility; Details is shown only for unsupported or incomplete detection states.
• Compatibility/diagnostic reports retain the Mac model identifier, platform support, Gaming eligibility, power/Restore state and full fan capability diagnostics, while removing tested/untested classification fields.

Cleanup

Removed obsolete production types:

• ModelValidationLevel
• ModelSupportRegistry
• IModelSupportRegistry
• ModelSupportDefinition

VerifiedHardwareModels.MacBookPro14_3 was also removed as an obsolete fixture constant.

VerifiedHardwareModels.MacBookPro16_1 intentionally remains only for bounded legacy/research uses, including the 0.4.0-compatible legacy ownership-marker schema and the dedicated physical SMC round-trip research tool. These uses do not grant application fan-write permission.

Safety boundary

No production changes were made under:

• FanControl/
• PowerManagement/
• Profiles/
• SettingsBackup/
• drivers/

No SMC key, payload, mask, RPM conversion, writer ordering, ownership journal, crash recovery, Restore ordering, or processor target was changed.

Validation

Local validation on the branch:

• git diff --check: PASS
• Release build: PASS, 0 warnings / 0 errors
• Tests: 632 / 632 PASS, 0 skipped
• release packaging: PASS
• prohibited release-content scan: PASS
• physical SMC writes: 0
• BCPC was not launched during this cleanup

Release note

This is a pre-release architecture/UI cleanup for the 0.5.0-rc.2 development target. It does not create or publish the release; final release-prep documentation and artifact checkpoint remain separate.

Maintainer audit PASS.

• Final head: 2a03bd6926dce4589c846725d4fa84610cbea236
• 2 commits, 39 changed files.
• SupportedIntelMac now derives from Apple hardware + Intel CPU without a model registry/whitelist.
• Legacy ModelValidationLevel / model-support registry types are removed.
• Supported UI no longer shows tested/untested or model-validation status; unsupported/incomplete platforms retain useful details.
• Compatibility/diagnostic reports retain model identity, platform support, Gaming eligibility, power/Restore state and live fan capability diagnostics.
• VerifiedHardwareModels.MacBookPro16_1 remains only for justified legacy schema-v1 downgrade compatibility and the bounded research round-trip tool; it is not a production writer permission gate.
• No production FanControl, PowerManagement, Profiles, SettingsBackup or driver write semantics changed.
• Local validation: 632/632 PASS, 0 warnings / 0 errors, diff-check PASS, packaging/safety scan PASS, zero physical SMC writes.
• PR CI #180 on the exact head: full Build and test SUCCESS including Gate 5D-B and release packaging validation.

Ready for squash merge.
