_list() pagination issue for smaller page size

[isivaselvan]

python-tfe version

0.1.2

Description

_list pagination in _base.py can repeatedly request page 1 and appear to hang (or loop indefinitely) when callers pass page[number] in params and use smaller page[size].

The current logic uses setdefault("page[number]", page) inside the loop.
When params already contains page[number] (for example from RunListOptions), setdefault does not overwrite it, so the request stays pinned to the same page even though page += 1 executes.

This is visible in examples/run.py when listing runs with smaller page sizes.

Testing plan

1. Export valid TFE credentials:
   - TFE_TOKEN
   - (optional) TFE_ADDRESS, TFE_ORG
2. Run:
   python examples/run.py --workspace-id=<workspace_id> --page-size=20
   -> completes.
3. Run:
   python examples/run.py --workspace-id=<workspace_id> --page-size=5
   -> repeatedly processes the same page and appears stuck.
4. Instrument request params/logs and observe:
   page[number] remains 1 across repeated requests.

Expected Behavior

Pagination should advance page-by-page (page[number]=1,2,3,...) and terminate normally when no more data is available.

Actual Behavior

For smaller page sizes, the same page is repeatedly requested, causing an apparent infinite loop / very long-running list call.

Additional Context

• Behavior depends on page size and number of records,
• larger page[size] may hide the bug,
• smaller page[size] makes it obvious.
• Likely fix: overwrite page[number] each loop iteration instead of using setdefault.
