O3-5452: Add encounter printing support for O3 forms

[ayesigaisaac]

Summary

Implements O3-5452 by adding backend support to print encounters based on O3 forms (JSON schemas).

What This PR Adds

• Encounter print API endpoints:
  • POST /ws/rest/v1/patientdocuments/encounters (queue print job)
  • GET /ws/rest/v1/patientdocuments/encounters/status/{requestUuid} (poll status)
  • GET /ws/rest/v1/patientdocuments/encounters/download/{requestUuid} (download PDF)
• Encounter report pipeline:
  • EncounterPdfReportManager
  • EncounterPdfReport
  • EncounterPdfReportRenderer
  • EncounterXmlBuilder
  • EncounterPrintingContext
• Default encounter print XSL-FO template:
  • defaultEncounterFormFopStylesheet.xsl
• Configurable header/footer/logo support via Initializer keys
• New privilege: App: Print encounter forms
• Added required module dependency on o3forms
• Added docs: readme/EncounterPrinting.md

Extra Cleanup Included

• Removed duplicate webservices.rest-omod-common dependency in api/pom.xml
• Fixed controller test wiring to use Spring injection
• Trigger response includes both uuid and requestUuid for compatibility

Validation

• ✅ mvn --% -Dmaven.repo.local=.m2 -Dproject.build.sourceEncoding=UTF-8 -DskipTests compile

Notes

• Full tests are environment-sensitive locally due to path/URI issues when Maven cache path contains spaces, but feature code compiles successfully and endpoints are implemented end-to-end.
