Fix: Enterprise cluster restore (postgres user via su)

Critical fixes for enterprise environments where dbbackup runs as
postgres user via 'su postgres' without sudo access:

1. canRestartPostgreSQL(): New function that detects if we can restart
   PostgreSQL. Returns false immediately if running as postgres user
   without sudo access, avoiding wasted time and potential hangs.

2. tryRestartPostgreSQL(): Now calls canRestartPostgreSQL() first to
   skip restart attempts in restricted environments.

3. Changed restart warning from ERROR to WARN level - it's expected
   behavior in enterprise environments, not an error.

4. Context cancellation check: Goroutines now check ctx.Err() before
   starting and properly count cancelled databases as failures.

5. Goroutine accounting: After wg.Wait(), verify all databases were
   accounted for (success + fail = total). Catches goroutine crashes
   or deadlocks.

6. Port argument fix: Always pass -p port to psql for localhost
   restores, fixing non-standard port configurations.

This should fix the issue where cluster restore showed success but
0 databases were actually restored when running on enterprise systems.

Download the appropriate binary for your platform
Make it executable (Unix-like systems): chmod +x dbbackup_*
Run: ./dbbackup_* --help

Interactive Mode

Launch the interactive TUI menu for easy configuration and operation:

# Interactive mode with TUI menu
./dbbackup_linux_amd64

# Features:
# - Interactive configuration settings
# - Real-time progress display
# - Operation history and status
# - CPU detection and optimization

Command Line Mode

Direct command line usage with line-by-line progress:

# Show CPU information and optimization settings
./dbbackup_linux_amd64 cpu

# Auto-optimize for your hardware
./dbbackup_linux_amd64 backup cluster --auto-detect-cores

# Manual CPU configuration  
./dbbackup_linux_amd64 backup single mydb --jobs 8 --dump-jobs 4
