✨ What is the change?

Adds a dedicated Presentation course phase covering the complete presentation lifecycle:

• staff-managed scheduling for individual students or teams, including overlapping slots and optional locations
• multi-file presentation material uploads through S3-compatible storage, with student deadlines at slot start
• predefined written feedback categories and independent or shared multi-instructor evaluation
• author-private drafts, submitted staff-visible evaluations, optimistic category revisions, and SSE live collaboration
• named feedback release, unrelease, revision, and re-release flows
• optional teams and teamAllocation phase inputs with dynamic team membership authorization
• Module Federation, Docker, CI, deployment, e2e, and documentation integration

The implementation is split into focused commits for core contracts, the React remote, the Go service, infrastructure, integration testing, and documentation.

📌 Reason for the change / Link to issue

Presentation scheduling, materials, and instructor feedback were previously handled outside PROMPT, resulting in fragmented workflows and no central record of evaluations.

Closes #1931.

🧪 How to Test

1. Copy .env.template and .env.dev.template to the local environment files and start the stack with docker compose up --build.
2. Add a Presentation phase in the Course Configurator. Leave the optional team inputs disconnected for individual mode, or connect teams and teamAllocation for team mode.
3. As a course lecturer, configure the target mode, feedback mode, and feedback categories.
4. Create overlapping or sequential slots, optionally add locations, and assign students or teams.
5. As an assigned student or team member, upload multiple presentation files before the slot starts and verify download/delete behavior.
6. As multiple editors, enter independent feedback or edit a shared form concurrently; verify live presence and optimistic conflict handling.
7. Submit all feedback, release it with a name, verify student visibility, then unrelease, revise, and release again.
8. Run go test ./... in servers/core, servers/team_allocation, and servers/presentation.
9. Run yarn workspace client typecheck, yarn workspace client build, and the Presentation remote's TypeScript, Biome, and production Rspack checks from clients/.
10. Run docker compose --env-file e2e/.env.e2e -f docker-compose.e2e.yml up --build --abort-on-container-exit --exit-code-from e2e-runner to exercise the Presentation Module Federation smoke test.
