Fix: Adjust pagination metadata when fetching projects with an assignee filter (#18)

### Description
This PR fixes a pagination bug in the `projects list` command.
Previously, when using filters that required fetching all pages and
processing them locally (e.g., filtering by `assignee`), the command
still parsed the raw API metadata for `totalPages` and `totalCount`.
This led to a misleading summary indicating many pages (like "Page
1/36") even when the local filtering only returned a handful of results
that fit completely on a single page.

The output logic has been updated so that when `fetch_all` is triggered,
the displayed "total pages" and "total items" are correctly calculated
from the localized result set.

### How to Test
1. Run `python -m conviso.app projects list --company-id <ID> --filter
assignee=<EMAIL>`.
2. Observe the output summary in the footer and title.
3. **Expected behavior:** The pagination metrics should represent the
exact number of matching projects found and should display as `page 1/1`
rather than retaining the unfiltered total counts from the initial API
metadata.
4. Run without the assignee filter and verify that normal pagination
limits remain standard and unbroken.
