chore(dynatrace): type the shared param map as unknown

Review follow-up. `Record<string, any>` in the block's params builder dropped
compile-time checking from every operation's shared params; `unknown` is
enough here since the values flow straight into the tool param maps. Matches
.claude/rules/sim-typescript.md, which sibling blocks (Datadog, Grafana)
still violate.
