fix(logger): guard fetchResource against unknown resource name

[WhereiamL]

Problem

The oxmysql:fetchResource net handler validates that data.resource is a string, but never checks that it actually exists in logStorage before indexing it:

const resourceLog = data.search
  ? logStorage[data.resource].filter((q) => q.query.toLowerCase().includes(data.search))
  : logStorage[data.resource];

If data.resource is any string that isn't a known resource key, logStorage[data.resource] is undefined and the .filter() call (search branch) throws Cannot read properties of undefined. The non-search branch then feeds undefined into resourceLog.slice() / resourceLog.length further down, which throws as well.

This is gated behind command.mysql, so it isn't a privilege issue, but a permitted user (or a UI request racing a resource that hasn't logged anything yet) can throw an unhandled exception in the handler.

Fix

Resolve the log entry once and bail out early when the resource has no stored queries, before any access.
