Is your feature request related to a problem? Please describe.
It is necessary to collect data on whether all configuration settings have been applied or whether some are pending applied.

Describe the solution you'd like
It is necessary to implement collection of additional data in the postgres/settings collector by query:

SELECT sourcefile, COUNT(*), 
(CASE applied WHEN 't' THEN 'true' ELSE 'false' END) as applied 
FROM pg_file_settings GROUP BY sourcefile, applied;

Example of result:

+-------------------------------------------+-------+---------+
|                sourcefile                 | count | applied |
+-------------------------------------------+-------+---------+
| /etc/postgresql/17/main/conf.d/test2.conf |     1 | true    |
| /etc/postgresql/17/main/postgresql.conf   |    26 | true    |
| /etc/postgresql/17/main/conf.d/test1.conf |     1 | true    |
| /etc/postgresql/17/main/conf.d/test3.conf |     1 | false   |
+-------------------------------------------+-------+---------+
