feat: optional parameter binding on query endpoint

[gregnr]

Adds an optional parameters field to the /query request body that allow consumers to bind parameters to a query. e.g.

{
  "query": "SELECT * FROM users WHERE id = $1 AND status = $2",
  "parameters": [1, "ACTIVE"],
}

This will help protect against SQL injection vulnerabilities.

nitpick

parameters?: unknown[] ? To match what's declared in the PostgresMeta.ts

Suggested change

	Body: { query: string; parameters?: any[] }
	Body: { query: string; parameters?: unknown[] }
