[MWPW-206112]Update supported file type for gen pres and interactive report to pdf only for viewer flow

[Ruchika4]

Summary

• Restricted gen-presentation-v2 and interactive-report verbs to PDF-only file uploads by replacing allowed-filetypes-study-spaces + allowed-filetypes-eml-msg-images with allowed-filetypes-pdf-only in action-binder.js
• Removed both verbs from nonpdfSfuProductScreen in target-config.json (non-PDF product screen is irrelevant when only PDF is accepted)
• Removed both verbs from wordPageCountVerbs in target-config.json (Word page count validation is no longer needed)
• Deleted the allowed-filetypes-eml-msg-images entry from limits.json as it was exclusively used by these two verbs and is now dead config

Test plan

• Upload a PDF to gen-presentation-v2 — should proceed normally
• Upload a PDF to interactive-report — should proceed normally
• Upload a non-PDF file (e.g. .docx, .pptx, .jpg) to either verb — should be rejected with a file type validation error
• Verify no regressions on other verbs that use allowed-filetypes-study-spaces (quiz-maker, flashcard-maker, mindmap-maker)
