What it does
  Updates a pirate record that’s already approved. Typical cases: the player renamed their character,
  or moved to a new account tag.
Form fields
  - Current account — must match exactly what’s in the list (e.g., 
SomeUser#12345). 
  - New in-game nickname — optional; leave empty to keep the current one.
 
  - New account — optional; must be 
Name#12345. If the new value already exists on another pirate, it’s rejected. 
Rules & feedback
  - Moderator-only.
 
  - You must change at least one thing (nickname or account).
 
  - On success you’ll see “✅ Pirate updated.” (ephemeral) and the public list refreshes.
 
  - A short mod-log entry is posted for audit (“✏️ Edited pirate …”).
