[👨🏻‍💻 Internal]: Make e2e tests run faster

[Kiryous]

"Set up Keep environment" step takes around 7min now.
This step is running docker compose up -d which involves building and starting your containers
The 7 minutes are likely spent mostly on:

Building the frontend Docker image (~4 mins for npm build)
Building the backend Docker image
Starting all services and waiting for them

[Kiryous]

Typical backend build:

Step	Description	Time
1-4	Initial setup (load definitions, metadata, context)	2.7s
5	Base image setup (python:3.11.10-slim-bullseye)	5.6s
6	Create keep user	0.7s
7	Set working directory	0.1s
8	Install poetry	20.2s
9	Create Python virtual environment	2.0s
10	Copy dependency files	0.0s
11	Export and install requirements	92.9s
12-14	Copy application code and examples	0.1s
15	Install application package	31.1s
16-18	Final image setup (copy venv, examples, set permissions)	3.6s
19-20	Export image and metadata	1.2s
Total	Complete build process	~160s

Key observations:

• Dependency installation (11) took the longest at ~93 seconds
• Poetry installation (8) and application installation (15) were also significant
• Most file operations were very quick (< 1s)
• The entire build process took approximately 2 minutes and 40 seconds
