feat(dashboard): model test-all with connection selector, usage by provider, combo enable toggle and showOnlyComboModels setting
- provider detail: Test All Models button runs every model (built-in + custom) with an optional connection selector; failed models can be disabled in bulk - bulk selected-model test now runs all connections in parallel (Promise.all) - usage overview: new 'Usage by Provider' table view (default) and a Provider column in Recent Requests; byProvider now tracks lastUsed - combos: per-combo enable/disable toggle; disabled combos are skipped by the routing engine (getComboModels/getComboModelsFromData) and model listing - settings: 'Only show combo models' toggle filters ModelSelectModal and the /v1/models response to models present in enabled combos
