What this PR does / why we need it?

supervisorctl status reports running process uptime as part of the process description, for example:

  pid 123, uptime 0:12:34
  pid 123, uptime 103 days, 0:12:34

  The previous parser used a fixed field index (fields[5]), which only worked for uptime values without the optional days segment. When the uptime contains days, only the day count was kept and the remaining time part was lost.

Summary of your change

• Parse RUNNING status details by locating the pid and uptime fields instead of relying on fixed indexes.
• Preserve the full uptime value by joining all fields after uptime.
• Add tests for standard Supervisor uptime formats with and without the optional days segment.

Please indicate you've done the following:

• Made sure tests are passing and test coverage is added if needed.
• Made sure commit message follow the rule of Conventional Commits specification.
• Considered the docs impact and opened a new docs issue or PR with docs changes if needed.

Fix supervisor uptime parsing when `supervisorctl status` reports an uptime with days.
