Fix: handle resource names with special characters in admin settings

[Elabyad247]

Closes #721

Fix aGetResourceSettings and getResourceSettings pattern matching in admin and admin2
The previous gsub calls had two bugs:

1. The leading '*','#','@' strip pattern was unanchored, so the character could be stripped from the middle of a name.
2. resName was interpolated into a Lua pattern without escaping, so resources whose names contain special characters (like -) would produce wrong results.
   Anchor both patterns with '^' and escape special characters in resName.

Tested in admin works correctly, but admin2 the value is not updating, You should restart admin2 or reconnect.

It looks like a pre-existing issue in admin2 unrelated to this issue/fix. Would you prefer I dig into it in this PR, or open a separate issue for it so this one stays scoped to #721?

Pull request overview

Fixes admin/admin2 resource-settings parsing so resource names containing Lua pattern characters don’t break matching, and so leading access markers are only stripped at the start of the key (closing #721).

Changes:

• Anchor the leading access-marker strip (*/#/@) to the start of the setting key.
• Escape resName before interpolating it into Lua patterns.
• Anchor the resName. prefix removal to the start (and end) of the string for exact matching.

I moved safeResName and pattern outside the loop to avoid repetitive computation.
