Bug report: Magic does not detect shorter Base58 strings as potential Base58 outputs

**Describe the bug**
The "Magic" option can detect longer Base58 strings, but not shorter ones.

**To Reproduce**
1.) The following are two strings and their Base58 encoded versions
a.) T1z_w0r^z_8y50m3+h1n8z -> PrMheqquboPDJxPyQSTsq7B4JV9Nvd
b.) w00f -> 43hiLM

Use them both with the "Magic" option

**Expected behaviour**
The Magic option detects that each input is Base58 compatible, and decodes them.

For the first option, it does:

For the second option, it does not - Even under intensive mode ("w00f" does not appear anywhere in the list even if you scroll down)

Start with the Magic option's Base58 detection path and compare how it handles the two encoded examples, especially the shorter "43hiLM" result. Done means Magic identifies both inputs as Base58-compatible and decodes them, including when intensive mode is enabled; add or update regression coverage if the project provides a relevant test location.
