Overview

This PR adds a per-doctor, tokenised ICS calendar feed so doctors can subscribe to their DocForum schedule from Google Calendar, Outlook, or any phone calendar. The feed is deliberately PHI-free: events contain only the time, the label DocForum appointment, and a deep link — no patient name, intake, or reason. Tokens are rotatable and revocable, and the endpoint supports ETag/Last-Modified so calendar clients can poll cheaply.

Changes

🔑 Doctor feed tokens

• [MODIFY] backend/src/modules/doctors/repositories/index.ts

  • Persist per-doctor feed tokens with rotation/revocation support (old token invalidated immediately on rotation).

• [MODIFY] backend/src/modules/doctors/services/index.ts

  • Issue, rotate, and revoke feed tokens; resolve a token to its owning doctor for feed generation.

📅 ICS feed

• [MODIFY] backend/src/modules/appointments/services/index.ts
  • Build the ICS payload for a doctor's appointments: UTC times with correct TZID handling, DocForum appointment summary, deep link, and STATUS:CANCELLED for cancellations so subscribed calendars update.
  • Compute ETag / Last-Modified validators for conditional requests.
  • No patient-identifying fields are emitted in any event property.

📚 Docs

• [MODIFY] docs/api/README.md
  • Document GET /calendar/:token.ics, token rotation/revocation, and how doctors subscribe from common calendar clients.

🚨 Malware scan: needs security review

@Philcsweb3 The automated scan of 4a38aa9 flagged code that can run on a maintainer's machine or in CI, or that hides what it contains. This PR won't be reviewed, and its CI won't be approved, until a maintainer has checked these:

Where	Rule	Why
docs/api/README.md:1	base64-file	Content is committed as base64. It hides what the file really contains, and merging overwrites the real file.

If this is a false positive, reply here explaining why and a maintainer will clear it. If it isn't intentional, remove it and push again: the scan re-runs on every push and updates this comment.

@Philcsweb3 The malware scan flagged docs/api/README.md because the whole file was committed as base64 text, not markdown. I decoded it: the content is just the API docs, nothing malicious, but merging it would replace the real docs with unreadable base64. Please commit the file as plain markdown (check git diff main -- docs/api/README.md shows readable text) and push. The scan re-runs automatically. CI is also failing on this branch, so please check the Backend job log once the file is fixed.

[github-actions]

@Philcsweb3 This PR now has merge conflicts with main, most likely because #140 (feat(auth): password reset flow with single-use, hashed, expiring tokens) was just merged, so it can't be merged until it's rebased:

git fetch upstream            # upstream = https://github.com/DocForum/docforum-core.git
git rebase upstream/main
# resolve the conflicts, re-run the tests, then:
git push --force-with-lease

The usual culprits are shared files like ROADMAP.md and ARCHITECTURE*.md. CI re-runs when you push, and the needs-rebase label is removed automatically once the conflicts are resolved.

_{Automated message. It won't repeat unless the PR conflicts again after your next push.}
