refactor keepass_discover module

[lodos2005]

Description

This PR completely refactors the keepass_discover module, removing its dependency on PowerShell and introducing a more efficient, tiered search strategy.

• Key Changes: Native Process Enumeration: Process discovery now uses impacket's TSTS.LegacyAPI instead of Get-Process.
• Tiered File Search: A new fast search (FILES) checks only common KeePass installation and configuration directories. The existing deep search (DEEP_FILES) now uses the native connection.spider() method for a comprehensive scan.
• Improved Module Options: DEFAULT: The new default option, combines process discovery with a fast file search. ALL: Combines process discovery with a deep file search for the most thorough scan.

Nice! Thanks for the PR!

Hey man! Thank you for the PR. I believe we should keep the Get-Process cmd thing because if RDP is not enabled on the remote host because if it's not, the named pipe won't be reachable.

This is the message I output with the --tasklist option:

So can you modify the PR to add this:

try:
     # get process via TST
except:
     #  If pipe not reachable (RDP disabled)
else:
    # Then get process via powershell / cmd
