fuzz: Add a test case for `ParseByteUnits()`
`ParseByteUnits()` is the only parsing function in `strencodings.cpp`
lacking a fuzz test. Add a test case to check the function against
arbitrary strings and randomized default_multiplier's.
What changed, and why it matters
This commit only adds a new fuzz test for an existing string-parsing helper called ParseByteUnits(). It does not change any production code, fix a bug, or alter behavior. Fuzz tests feed random inputs to functions to help find crashes or bugs during automated testing, but the function itself is unchanged.
No security action needed; this is a test-only addition. Continue normal review and fuzzing pipeline monitoring.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff adds a fuzz-target block in src/test/fuzz/string.cpp that exercises ParseByteUnits(random_string_1, default_multiplier) with a randomized ByteUnit default_multiplier. No implementation code in strencodings.cpp or elsewhere is modified. There is no patch to a vulnerability.
