refactor(app): rename Component* UI widgets to accurate domain names

The dashboard widgets were named after the old 'component' concept. Renamed
each to what it actually renders:

- ComponentCard  → ServiceCard      (ServiceSummary, /services/, service actions)
- ComponentTable → ProgramTable     (ProgramSummary[], the program catalog)
- ComponentEditor→ DeploymentEditor (DeploymentDetail, the unified type)
- ComponentFields→ DeploymentFields (AnyDetail)
- AddComponent   → AddDeployment

Also purged the domain term 'component' from the rest of the app: the
useComponent hook → useDeployment, ConfigPanel + the three detail pages'
`component` prop/var → `deployment`, and the gateway/node table headers
(Component → Program / Deployment). Props renamed to match (component →
service / program / deployment). The React UI directory app/src/components/
keeps its conventional name.

App type-checks and builds clean.
