Refactor moderation flags for granular control
- Rename `reportOnly` to `reportAcct` and `commentOnly` to `commentAcct`
for clarity.
- Introduce `toLabel` flag to explicitly manage item labeling.
These changes allow independent control over labeling an item,
reporting its author, or commenting on the author's account.
- Remove non-functional pre-check for existing labels before applying new ones in handle and profile checks.
- Add checks for starter pack content (name, description) and known vector authors.
- Implement `createPostReport` function for reporting specific posts.
- Update `checkHandle` signature for direct parameter passing.
- Populate predefined moderation lists.
