fix(e2e): use uv run for import test Python scripts (#845)

* fix(ci): unpin boto3 in e2e workflow

The pinned boto3==1.38.0 did not include the bedrock-agentcore-control
service model, causing import-resources e2e tests to fail with
UnknownServiceError. Using latest boto3 ensures new AWS services are
always available.

* fix(e2e): use uv run for import test Python scripts

The import e2e tests call python3 directly to run setup scripts that
use boto3. On CI runners, the system-installed boto3 is too old to
include the bedrock-agentcore-control service model. pip install boto3
installs to user site-packages which the child process doesn't pick up.

Switch to uv run --with boto3 python3 so the scripts always get a
current boto3 in an isolated environment. Remove the now-unnecessary
pip install step from the workflow.
