fix(catalyst-ui): ExecutionLogs uses API_BASE so /api/ → /sovereign/api/ routes correctly (#305 follow-up 4) (#332)

Pre-existing bug exposed by #305: ExecutionLogs fetched
`/api/v1/actions/executions/{id}/logs` directly instead of going
through API_BASE (`${BASE}api`). Under Vite's `/sovereign/` base path,
the Traefik ingress only routes `/sovereign/api/...` — bare `/api/...`
returns 404.

Live evidence after #328 (jobId raw colon fix):
  GET /sovereign/api/v1/deployments/.../jobs/{id} → 200  (FE rewire OK)
  GET /api/v1/actions/executions/{realExecId}/logs → 404 (this bug)

Note that the executionId in the failing URL is a real 32-char hex
(5f59cb0bc9df2c720b4cf07989e4dc4f), not the synthetic `:latest` —
proving the rewire in #307 + the colon fix in #328 both worked. Only
the logs URL prefix remained wrong.

Fix: import API_BASE; use `${API_BASE}/v1/actions/executions/...`.
Per docs/INVIOLABLE-PRINCIPLES.md #4 (never hardcode URLs in app
source) — the original direct `/api/...` was a violation that this
PR settles permanently.
