Remove unused DOTS tracker feature

[avazirna]

Product Description

This PR removes the DOTS (Directly Observed Therapy) tracker feature, as it is no longer in use. The feature was originally developed for the UATBC project to track medication intake by program beneficiaries. Since it is obsolete, the associated functionality and related screens have been removed from the application. The main screen that were part of this feature include:

Calendar	Day period	Medication intake

Technical Summary

Retires DotsEntryActivity and its supporting classes/resources. The activity was launchable only via the org.commcare.dalvik.action.DotsEntry intent action, declared exported="false" so only same-app callers could
fire it — and no in-tree caller fires that action. Neither commcare-android nor the libs/commcare-core submodule contains any reference to the action string or to the deleted classes outside the DOTS files themselves. Last substantive change to any of these sources was a 2025-09 lint pass; no feature work in years.

Safety Assurance

Safety story

• Static verification on the branch tip: git grep for every removed class name, every removed resource ID, and the intent action string org.commcare.dalvik.action.DotsEntry returns zero matches in both app/ and the libs/commcare-core submodule.
• Commit ordering keeps the manifest valid at every intermediate step (manifest dropped first, then classes, then resources — never a manifest pointing at a missing class).
• Data impact: none expected. The activity serialized state into its own bundle key (DOTS_DATA); since nothing on master launches it, there are no in-flight payloads to migrate.

Labels and Review

• Manual QA: not required — feature is unreachable on master.
• RELEASES.md: no update needed (no behavior change).
• Risk: low (pure deletion, statically verified).
• Reviewers: ping someone familiar with the historical DOTS tracker
  and the XForm intent-callout dispatch path.

📝 Walkthrough

Walkthrough

This pull request removes the DOTS (Directly Observed Therapy Short-course) medication tracking feature entirely from the CommCare Android application. The removal includes deregistering the DotsEntryActivity from the manifest and eliminating the DotsHomeView UI component that displayed a calendar grid of medication days. The feature removal also extends across the codebase to eliminate the supporting data model (DotsData), listener interface (DotsEditListener), detail editing view (DotsDetailView), and all associated layout XML and drawable resources.

@ctsims I've been planning to remove this feature for some time. Any concerns with this removal?
