feat(RM-24): Add PanelHereMention functionality and integrate into Database

[DanPlayz0]

This pull request introduces a new feature to handle "here" mentions in panels by adding a new PanelHereMention struct and its associated methods. The changes involve updates to the database.go file and the addition of a new file panelmentionhere.go.

Key changes:

Database schema changes:

• Added a new field PanelHereMention to the Database struct in database.go to manage "here" mentions.
• Updated the NewDatabase function to initialize the new PanelHereMention field.
• Modified the CreateTables method to include the new PanelHereMention table creation.

New functionality:

• Created a new file panelmentionhere.go that defines the PanelHereMention struct and its methods for managing "here" mentions in panels. This includes methods for creating the table schema, checking if a panel should mention "here", and setting the "here" mention status.
