Fixes issue #7346 where proxy startup failed on non-root servers due to
bash syntax errors when control structure keywords like 'for', 'do', 'done',
'break', and 'continue' were being prefixed with 'sudo'.
Added comprehensive exclusion list including for/while/until/case/select
loops, conditionals (if/then/else/elif/fi), and loop control keywords
(break/continue). Also excludes comment lines starting with '#'.
All 37 unit tests pass, including new tests for each bash control structure.

Fixes Docker installation failures on non-root servers by properly handling
complex shell commands with pipes and operators. Previously, the sudo parser
would insert sudo throughout command chains, breaking pipe structures like
'curl URL | sh || curl URL2 | sh'.
The fix detects complex piped commands (containing '| sh', '| bash', or
pipes combined with && or || operators) and wraps them in 'sudo bash -c'
instead of inserting sudo mid-command. This preserves the command structure
and prevents syntax errors.
Changes:
- Detect complex piped commands in parseCommandsByLineForSudo
- Wrap complex commands in 'sudo bash -c' with proper quote escaping
- Preserve original behavior for simple commands
- Add 27 comprehensive unit tests covering all scenarios
Fixes#7116
