Sanitize printer serial numbers in support bundle logs (Issue #216)

Browse Source 
The support bundle states that printer serial numbers are NOT collected,
but they were appearing in debug logs. Added regex to sanitize Bambu Lab
serial numbers (00M/01D/01S/01P/03W prefix + alphanumeric) while keeping
the prefix for debugging context.

Example: [01D00A12345678] -> [01D[SERIAL]]

Closes #216
