fix: enforce log message trailing period rule

[palakkhinvasara]

#44632
Add a custom logger-static-message Oxlint rule to enforce Renovate logging conventions.

• Require warn, error, and fatal log messages to use static strings.
• Prevent logger messages from ending with a trailing period.
• Require error objects in logger metadata to use the err key instead of error.
• Apply these checks to production code under lib/.
• Fix existing logger violations across the codebase.

Context

• This closes an existing Issue
  Closes: #44632 — lint: don't allow trailing . in log messages

• This doesn't close an Issue, but I accept the risk that this PR may be closed if maintainers disagree with its opening or implementation.
