`comp query` fails for upstream-type components with "invalid spec source type: upstream"

### Issue Description

## `comp query` fails for upstream-type components with "invalid spec source type: upstream"

### Description

`azldev comp query -p ` fails for any component using the default upstream spec source type (bare inline entries). It incorrectly rejects `upstream` as an invalid spec source type.

### Repro

```bash
# Any bare upstream entry triggers this — not component-specific
azldev comp query -p coreutils
```

### Error

```
ERR Error: failed to parse spec for component "coreutils":
component "coreutils" has invalid spec source type: upstream
```

### Expected

`comp query` should resolve the upstream spec (clone from Fedora dist-git) and display spec details, the same way it works for local-spec components like `azurelinux-release`.

### Workaround

Other commands handle upstream components correctly — `comp list`, `comp prep-sources`, and `comp build` all work fine. Only `comp query` is affected.

### Evidence that upstream resolution works elsewhere

```bash
# All succeed for the same component:
azldev comp list -a | grep coreutils                       # Shows "Upstream: fedora 43"
azldev comp prep-sources -p coreutils -o "$(mktemp -d)"    # Clones and downloads sources
azldev comp build -p coreutils                              # Builds successfully
```

### Likely Cause

`comp query` has a separate code path for resolving spec source types that doesn't handle the implicit/default `upstream` type, while the other subcommands use a shared resolution path that does.


### Expected Changes

comp query should function correctly when querying basic components from https://github.com/microsoft/azurelinux/tree/tomls/base/main
