(chore) Normalize ampathforms filenames

[denniskigen]

Summary

Rename form and translation files under configuration/backend_configuration/ampathforms/ and configuration/backend_configuration/ampathformstranslations/ to a consistent shape:

• snake_case throughout (no spaces, no PascalCase, no hyphens within the base name)
• -core_demo package suffix applied uniformly (was previously on 5 of 8 forms)
• Fix typo: stuctured_soap_note → structured_soap_note

Renames

ampathformstranslations/

Old	New
Test Form 1_translations_fr-core_demo.json	test_form_1_translations_fr-core_demo.json
soap_note_translations_en.json	soap_note_translations_en-core_demo.json
soap_note_translations_fr.json	soap_note_translations_fr-core_demo.json

Safety

No content changes. Internal name and uuid fields inside each JSON are untouched, so:

• The form engine (openmrs-esm-form-engine-lib) looks up forms by UUID or internal name via /ws/rest/v1/form/... — filename is not consulted.
• Translation files bind to forms via their internal form name field, not filename.
• No OpenMRS module reads these filenames directly (unlike the addresshierarchy domain, cf. ADDR-138: Rename addressConfiguration-core_demo.xml to addressConfiguration.xml #7).

Note on the translation filename test_form_1_translations_fr-core_demo.json: its internal form field is "Test Form 1", which matches the internal name of test_form-core_demo.json. The filenames differ only in the trailing _1, which is cosmetic — binding is by internal name.

Out of scope

• Whether to drop the -core_demo suffix repo-wide (decision with cross-package implications, ref. discussion in ADDR-138: Rename addressConfiguration-core_demo.xml to addressConfiguration.xml #7).
• Possible duplication between soap_note_template-core_demo.json and structured_soap_note-core_demo.json — not addressed here.
