test: add E2E tests for assignAllTeamMembers with attribute segment filters (calcom#27680)

* test: add E2E tests for assignAllTeamMembers with attribute segment filters

Cover all 4 attribute types (SINGLE_SELECT, MULTI_SELECT, TEXT, NUMBER)
with booking flow verification plus edge cases (no match, all match).

* fix: use auto-retrying assertion for no-match edge case test

Replace flaky waitForTimeout(2000) + count check with Playwright's
toHaveCount(0, { timeout: 15000 }) which retries until availability
settles, preventing CI timing issues.

* test: add exclusion tests for members without attribute assigned

Add 4 new E2E tests covering the case where team members have no
attribute assigned at all (not just a different value). Each attribute
type (SINGLE_SELECT, MULTI_SELECT, TEXT, NUMBER) is tested to verify
that members without the attribute are excluded from the booking pool.

* test: add negation operator tests and restructure exclusion tests

- Restructure 'Members without attribute assigned' tests: assign
  matching attribute to teammate-1 (not owner) so round-robin can't
  coincidentally pass when the bug exists
- Add 4 negation operator tests (select_not_any_in, multiselect_not_some_in,
  not_equal for TEXT and NUMBER) that verify unassigned members should
  match negation filters. Marked with test.fail() as they confirm a
  known bug where getLogicResultForAllMembers skips members without
  attribute assignments entirely.
- Add edge case: no members have attribute assigned -> no available slots
