Remove non-inclusive language (#4738)

[lukaszgryglicki]

Remove non-inclusive language everywhere (about 99%, requested in #4738) except:

• API parameter names and API URLs (that would require updates in acs-cli, lfx-gateway and all consumers).
• Dynamo DB table names and dynamo DB item property names (that would require database migration).

Pull Request Overview

This PR removes non-inclusive language throughout the codebase by replacing "whitelist" terminology with "allowlist" and updating references from "master" to "main" branch names. The changes maintain backward compatibility by preserving API parameter names, URLs, and DynamoDB table/property names that would require breaking changes across multiple systems.

• Updates code references, comments, variable names, and function names from "whitelist" to "allowlist"
• Changes default branch references from "master" to "main"
• Adds compatibility comments explaining why certain API and database names cannot be changed yet
