Fever integer type for numbers (#2946)

* Fever integer type for feed ID

#Fix
https://github.com/FreshRSS/FreshRSS/issues/2940#issuecomment-623022435

* Fix feed_id

* Ensure string for entry ID

To be compatible with 32-bit platforms.
Before, the type was inconsistent depending on architecture + database

* Integer for entry count functions
