[BUG] Bare except: blocks in original algorithm implementations

[Devguru-codes]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

All 14 bare except: blocks catch every exception including KeyboardInterrupt, SystemExit, MemoryError, etc. This:

1. Makes debugging impossible - errors are silently swallowed
2. Violates PEP 8 ("Never use a bare except:")
3. Hides real bugs (e.g. TypeError, ValueError from bad input)

Screenshots [optional]

No response

Steps To Reproduce

• src/original/fitting/OGC_AmsterdamUMC/LSQ_fitting.py -13 occurrences
• src/original/fitting/PV_MUMC/triexp_fitting_algorithms.py -1 occurrence

Expected behavior

Help in debugging the errors

Additional context

Replacing each bare except: with the most specific exception type(s) that the try block can raise.
