Fix five bugs found during code review

[T0pCyber]

• Initialize-HawkGlobalObject: Remove unreachable dead-code EndDate block
  (the preceding while-loop guarantees $EndDate is always set)
• Initialize-HawkGlobalObject: Fix StartDate off-by-one when user enters
  days in interactive mode; $EndDate already carries the +1 day offset so
  the extra AddDays(-1) produced a 31-day window for a 30-day request
• Out-Report: Replace broken .identity.contains() entity-existence check
  with a correct Where-Object query; the old call always returned false,
  causing duplicate entity nodes in the XML report file
• Test-HawkGlobalObject: Correct the .EXAMPLE help text which stated the
  opposite of the actual return semantics ($true = needs init, not initialized)
• Start-HawkTenantInvestigation / Start-HawkUserInvestigation: Clarify
  the comment above the Test-HawkGlobalObject call so it matches the
  function's real meaning

Pull request overview

This PR addresses five bugs discovered during code review, primarily focusing on fixing incorrect logic in date handling, documentation errors, and an XML entity duplicate issue. While resolving a merge conflict, it also appears to introduce documentation changes regarding telemetry data collection.

Changes:

• Removed unreachable dead code in Initialize-HawkGlobalObject that attempted to set EndDate after a while-loop already guaranteed it was set
• Fixed an off-by-one error in StartDate calculation that caused a 31-day window when requesting 30 days
• Corrected broken entity existence check in Out-Report that was causing duplicate XML nodes
• Fixed misleading documentation in Test-HawkGlobalObject that stated the opposite return semantics
• Clarified comments in investigation functions to correctly describe when initialization occurs

• The variable $StartDays is used here but is never explicitly initialized before the StartDate while loop. When a user enters a specific DateTime (rather than a number of days), $StartDays remains uninitialized. While PowerShell treats uninitialized variables as $null and the comparison "$null -gt 0" evaluates to $false (making the code work correctly), it's better practice to explicitly initialize $StartDays to 0 before the StartDate while loop for clarity and to avoid potential issues with strict mode.

        if ($StartDays -gt 0) {

• The removed line "No environmental or system data." appears to have been deleted during merge conflict resolution. This should be verified - if environmental or system data is now being collected, the documentation accurately reflects this change. However, if this deletion was unintentional and no environmental/system data is collected, this line should be restored to maintain accurate documentation of what data is not collected.

- No user-identifiable data.

• This PR adds "Region of use" to the collected data list, which appears to be outside the scope of the stated purpose ("Fix five bugs found during code review"). This change introduces a new data collection practice that should be documented in the PR description and may require additional review or discussion. If region data is not actually being collected in the current code, this documentation change is inaccurate and misleading.
