Replace type suppression with proper type narrowing in rating middleware

[Copilot]

Addresses review feedback on #105 regarding the @ts-ignore comment in the rating middleware. The regex validates vote is either "up" or "down", but TypeScript infers string from the regex match, requiring type assertion for createRating().

Changes

• Replaced @ts-ignore with explicit type guard checking for 'up' or 'down'
• TypeScript now narrows the type through control flow analysis
• Added defensive 400 error for invalid vote values (unreachable due to regex, but satisfies type checker)

Example

Before:

let vote = match[2];
// @ts-ignore (Type-safety is enforced by regex)
await directus.createRating(vote, podcast);

After:

let voteString = match[2];
if (voteString !== 'up' && voteString !== 'down') {
  throw createError({ statusCode: 400, message: 'Invalid vote value' });
}
const vote = voteString;  // TypeScript infers "up" | "down"
await directus.createRating(vote, podcast);
