fix: propagate projectId into wakeup context and support identifier lookup (#6026)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The server's heartbeat/wakeup pipeline resolves which project
workspace an agent run should bind to
> - `enqueueWakeup` resolves an issue (and therefore a project) before
scheduling a run, but the resolved `projectId` was never written back
into `enrichedContextSnapshot.projectId`, so `resolveWorkspaceForRun`
always saw `contextProjectId === null`
> - When the `issueProjectRef` DB lookup also returned null (e.g.
identifier-style id like `ENV-13`, not a UUID), workspace resolution
fell through to the `agent_home` fallback instead of the correct project
workspace
> - Surfaced while running the QA matrix on sandbox/SSH — runs were
ending up in the wrong workspace
> - This pull request stores the resolved `projectId` back into context
and replaces the raw UUID-only DB query with `issuesSvc.getById`, which
accepts both UUIDs and identifiers and canonicalizes `context.issueId` /
`context.taskId` to the UUID on identifier hits
> - The benefit is that wakeups triggered with identifier-style ids
correctly bind to their project workspace instead of silently degrading
to `agent_home`

## What Changed

- In `enqueueWakeup`, after the issue resolves, write `projectId` back
into `enrichedContextSnapshot.projectId` so downstream workspace
resolution can use it.
- Replace the raw UUID-only DB query for the issue with
`issuesSvc.getById`, which handles both UUIDs and identifiers (e.g.
`ENV-13`).
- On an identifier hit, canonicalize `context.issueId` and
`context.taskId` to the resolved UUID.

## Verification

- Trigger a wakeup with an identifier-style id (`ENV-13`) on the dev
instance and confirm the run binds to the correct project workspace
instead of `agent_home`.
- Confirm UUID-style wakeups still resolve to the same project workspace
as before.

## Risks

- Low risk. Scope is a single function in
`server/src/services/heartbeat.ts` (+20/-7). Failure mode if regressed
is the prior behavior (fallback to `agent_home`).

## Model Used

- Claude (Anthropic), `claude-opus-4-7`, via Claude Code / Paperclip
`claude_local` adapter.
