Find-DbaObject - Add unified command to search database objects by name

[andreasjordan]

Closes #9245

Adds Find-DbaObject, a unified command to search all database object types by name pattern, with optional column name searching.

What does this PR do?

• Searches object names across tables, views, stored procedures, functions, synonyms, and triggers
• Optionally searches column names with -IncludeColumns
• Filter by object type with -ObjectType
• Uses T-SQL against sys.objects and sys.columns for performance
• Full regex support for pattern matching

Root cause: The test searched for syslogins (a system view in the master database) with IncludeSystemDatabases = $true, but the T-SQL query always filters AND o.is_ms_shipped = 0 unless IncludeSystemObjects is also set. Since syslogins has is_ms_shipped = 1, it was being excluded.

Fix: Added IncludeSystemObjects = $true to the test splat in tests/Find-DbaObject.Tests.ps1:229 so the test correctly finds the syslogins system view when searching system databases.

Fixed failing test

• Gather context
• Read test file and implementation to identify the issue
• Fix the failing test
• Commit and push

Root cause: The test tried to find syslogins (a Microsoft-shipped system view with is_ms_shipped = 1) to verify IncludeSystemDatabases works. This is unreliable — system objects vary across SQL Server versions and configurations.

Fix: Rewrote the "System databases" context to follow the established dbatools pattern used by Find-DbaView and Find-DbaStoredProcedure tests:

1. BeforeAll: Create a user-created table (t_dbatoolsci_systemdb_<random>) in master
2. It: Search for it with IncludeSystemDatabases = $true — verifies both that system databases are searched AND that the correct database name appears in results
3. AfterAll: Drop the table from master

No IncludeSystemObjects needed since the test table is user-created (not is_ms_shipped).
