bug: createsiteusers/deletesiteusers line counts and output format incorrect

[jacalata]

Summary

createsiteusers and deletesiteusers show incorrect line counts and inconsistent output format, discovered during live server output comparison testing (2026-07).

---

createsiteusers — "Lines skipped" shows error count, not skipped count; output inconsistent with tabcmd 1

Current output (error case):

Lines processed: 1
Lines skipped: 1
Number of users added: 0
Error details:
['ServerResponseError']

Expected (tabcmd 1):

===== Lines processed: 1
Lines skipped: 0
Number of users added: 1
Number of errors: 0

Lines skipped is being populated with number_of_errors instead of a genuine skip count. There is no separate "Number of errors" line. The error_list is logged as a raw Python list rather than formatted per-line.

Location: tabcmd/commands/user/create_site_users.py — summary block at the end of run_command.

---

deletesiteusers — "Lines processed" shows 0 even when a user was attempted

Current output:

Lines processed: 0


    404: Item not found
        Item not found: [Users] anyoung@salesforce.com
Lines processed: 0
Number of errors: 1
Error details:

Issues:

• Lines processed: 0 even though 1 user was attempted
• "Lines processed" appears twice
• Empty "Error details:" section despite an error being shown above it
• Blank lines and indented error text mixed into the summary block

Location: tabcmd/commands/user/delete_site_users_command.py

Relationship to #429

Issue #429 item 4 fixes the createsiteusers error message format (str(e) instead of e.__class__.__name__). The counting and structural output issues are tracked here separately.
