fix(components): resolve stack version for config GET via --stack-version flag (CLI-124)

[fhacloid]

Root cause

`GetComponentConfig` made a bare `GET .../config` with no query params. The API returns the config pinned to an older stack commit when `service_catalog_source_version_id` is omitted — the console always passes it (`?service_catalog_source_version_id=`), so the CLI was returning stale fields (missing new widgets, new credential keys, etc.).

Evidence:

• Console call: `GET .../config?service_catalog_source_version_id=14` → latest config ✓
• CLI call (before fix): `GET .../config` → stale config, missing fields ✗

Fix

`GetComponentConfig` now:

1. Fetches the component to get its stack ref
2. Calls `resolveStackVersion(org, stackRef, tag, branch, hash)` — same resolution logic used by `GetComponentStackConfig`
3. Passes the resolved ID as `?service_catalog_source_version_id` to the config endpoint

When no version flag is given (default), all three args are empty → `resolveStackVersion` returns the catalog-repo branch head, which is exactly what the console does.

User-facing flags

`cy component config get` now accepts `--stack-version` via `cyargs.AddStackVersionFlags` — same surface as every other stack command:

Form	Behaviour
(omitted)	auto-resolves to catalog branch head (default, matches console)
`--stack-version=tag:v1.2.3`	pins to that tag
`--stack-version=branch:main`	pins to that branch
`--stack-version=sha:`	pins to that commit
`--stack-version=version:14`	passes ID 14 directly — bypasses resolution (debug use)

`ResolveStackVersionArg` returns an informative error if `version:` is used with commands that don't support raw IDs.

Changed files

File	Change
`cmd/cycloid/middleware/organization_components.go`	Core fix: resolve via stack ref + pass version ID as query param; bypass resolution when versionID != 0
`cmd/cycloid/middleware/middleware.go`	Interface: add `versionTag, versionBranch, versionCommitHash string, versionID uint32` params
`cmd/cycloid/components/config_get.go`	`AddStackVersionFlags` + `ResolveStackVersionArg`; `version:` handled before resolution
`cmd/cycloid/components/create.go`	Pass `"","","",0` (auto-resolve latest)
`cmd/cycloid/components/update.go`	Pass `"","","",0` (auto-resolve latest)
`internal/cyargs/stacks.go`	`version:` case in `ResolveStackVersionArg` (informative error); flag description updated
`cmd/cycloid/middleware/offline/component_config_test.go`	4 offline tests: raw ID, branch→ID, tag→ID, default→branch head

Tests

Four offline tests (no backend required) — all pass:

• `TestGetComponentConfig_RawVersionID` — `version:14` → 1 call, `service_catalog_source_version_id=14`
• `TestGetComponentConfig_BranchResolvesVersion` — `branch=main` → ID 99
• `TestGetComponentConfig_TagResolvesVersion` — `tag=v1.2.3` → ID 77
• `TestGetComponentConfig_AutoResolvesLatestVersion` — no version → catalog branch head ID 99

`golangci-lint run --new-from-rev=develop` → 0 new issues.
