[Elastic Assistant] Fix authentication issue in shared conversations Cypress test

[enriquesanchez-elastic]

Summary

Fixes a 401 authentication error occurring in the AI Assistant shared conversations Cypress test when running in serverless environments.

Problem

The test was failing during the before hook with a 401 Unauthorized error when attempting to logout using the logout() function. This was specifically happening in serverless environments where the authentication flow differs from ESS.

Solution

Replace logout() with cy.clearCookies() in the before hook. This approach:

• Is already used successfully throughout the rest of the test file
• Is the established pattern for user switching in Cypress tests
• Works correctly in both ESS and serverless environments

Changes

• x-pack/solutions/security/test/security_solution_cypress/cypress/e2e/ai_assistant/shared_conversations.cy.ts: Replace logout() call with cy.clearCookies() in line 93

Testing

• Verified the change follows the existing pattern in the same test file
• Confirmed cy.clearCookies() is used in lines 175, 209, 233, 258 for user switching

Saved Objects .kibana field count

Every field in each saved object type adds overhead to Elasticsearch. Kibana needs to keep the total field count below Elasticsearch's default limit of 1000 fields. Only specify field mappings for the fields you wish to search on or query. See https://www.elastic.co/guide/en/kibana/master/saved-objects-service.html#_mappings
