enhance ps_everywhere with UID tracking and fix spindump hardcoded UID

[itayfoT]

• Store UID/euid/auid in Event data
• Fix hardcoded uid=501 in spindumpnosymbols.py - now extracts actual UID from raw data
• Add extract_euid_from_tccd_message() for better TCCD log parsing
• Improve process uniqueness checking with (process, uid) tuples
• Maintains backward compatibility when UID is None
• Enrich ps_everywhere with process names also from log messages

that's a lot of changes in one PR !
I already integrated the spindump fix in 29a09e1 . thanks for that.

I am a bit worried on the part (co-)authored by Claude, also the copyright ownership uncertainties.

I'll try to review the bigger code change asap. Thanks for the contribution.
It looks unit tests are also breaking.
