refactor: rename Convert-ToTypeValue to Convert-ToTypedValue (missing 'd')

[HeyItsGilbert]

Summary

The private function is named Convert-ToTypeValue (no d). The test file, call site in Test-Condition.ps1, and every other function in the module (e.g., Test-TypedValue) use Typed. The source file and function declaration are the odd ones out.

Files Affected

File	Change
Gatekeeper/Private/Convert-ToTypeValue.ps1	Rename file to Convert-ToTypedValue.ps1
Gatekeeper/Private/Convert-ToTypeValue.ps1:1	Rename function declaration from Convert-ToTypeValue to Convert-ToTypedValue
Gatekeeper/Gatekeeper.psm1	Update dot-source path if hardcoded
tests/Convert-ToTypedValue.tests.ps1	Already correct — no change needed

Notes

• Good first issue
• The call site Test-Condition.ps1:88 already uses Convert-ToTypedValue — so either the function name was wrong from the start, or it was renamed without updating the source file
• Found by Brent Tlackburn and Shawn Wee!-ler
