Fix sdk-e2e-test: ensure DB is ready before server starts (#19583)

## Summary

- The `sdk-e2e-test` CI job has been failing since at least April 9th
because the nx dependency graph runs `database:reset` and
`start:ci-if-needed` in **parallel** — neither depends on the other. The
server starts before the DB tables are created, crashes with `relation
"core.keyValuePair" does not exist`, and `wait-on` times out after 10
minutes.
- Replace the `nx-affected` orchestration for e2e with explicit
**sequential** CI steps: build → create DB → reset DB → start server →
wait for health → run tests.
- Add server log dump on failure for easier future debugging.

## Root cause

In `packages/twenty-sdk/project.json`, the `test:e2e` target has:

```json
"dependsOn": [
  "build",
  { "target": "database:reset", "projects": "twenty-server" },
  { "target": "start:ci-if-needed", "projects": "twenty-server" }
]
```

Since `database:reset` and `start:ci-if-needed` don't depend on each
other, nx can (and does) run them concurrently. `start:ci-if-needed`
fires `nohup nest start &` and immediately completes. The server process
tries to query `core.keyValuePair` before `database:reset` creates it →
crash → wait-on timeout → job failure.
