What does this PR do?:
Apply the configured Google Java Format 1.30.0 output to 214 Java files across five modules. This is the second draft in the PROF-16537 stack, based on #955 rather than main.

Motivation:
The Java formatting gate restored by #955 rejects the existing source layout. Separating the migration lets reviewers inspect the small build repair without the formatting diff. This PR changes no formatting scope, exclusions or checks.

Additional Notes:

• Review stack: fix(build): register Java formatting lazily and update formatter [PROF-16537] #955 (build fix) → style(java): apply configured Java formatting [PROF-16537] #957 (Java formatting) → chore(java): address static analysis follow-ups [PROF-16537] #958 (Java quality follow-ups).
• Changes include import removal/reordering, comment reflow, indentation and equivalent modifier ordering. This is not literally a whitespace-only diff. No build configuration or native source changes are included.
• Required copyright changes add 50 missing headers and update 15 year ranges. Foreign attribution is preserved.
• The first two changes require integration with a passing formatting gate. This review stack does not make fix(build): register Java formatting lazily and update formatter [PROF-16537] #955 merge-ready on its own.
• This is mechanical source migration, not a fresh subsystem behavior audit. Integration with current main remains unqualified; no merge or ready transition is requested.

How to test the change?:
Validation covers the exact formatting commit on macOS arm64 with build JDKs 21.0.12 and 25.0.4.1. The separately reviewed stacked range retains those same source bytes.

• passed: full root spotlessCheck --rerun-tasks --no-build-cache --max-workers=2 through ./.claude/commands/build-and-summarize on both JDKs, without file scoping or extra exclusions.
• passed: all nine convention tests on each JDK, including real Java 8 compilation and class-file version 52.
• passed: nine affected JavaCompile tasks on each build JDK. The demo retains its configured JDK 21 compiler in both runs.
• passed: executed source-quality, copyright, CLAUDE, knowledgebase and whitespace checks. ELF signal-reachability checking is unavailable on macOS.
• passed: independent 214/214 formatter/header reconstruction and unchanged literal-token lists, plus independent review of this exact stacked range.
• inconclusive: current-main integration and CI for this newly stacked PR. Local or prior combined-PR results do not establish their success. No profiler/native runtime or sanitizer suite was run for this mechanical change.

For Datadog employees:

• If this PR touches code that signs or publishes builds or packages, or handles
  credentials of any kind, I've requested a security review (run the dd:platform-security-review
  skill, or file a request via the PSEC review form).
  bewaire also runs automatically on every PR.
• This PR doesn't touch any of that.
