Normalize indentation, spacing and PHP/HTML formatting in application/views/notes/main.php and application/views/notes/station_diary_print.php. Changes are purely cosmetic (whitespace, indentation, minor spacing around concatenation and tags, and newline adjustments) to improve readability and consistency; no functional logic was modified.
Add a Station Diary print feature: controller Notes.php now sets a has_diary_entries flag for the main notes view and adds a station_diary() action that loads Station Diary entries and renders a print-friendly view. The notes main view conditionally shows a "Station Diary" button that opens the print page in a new tab. A new view notes/station_diary_print.php provides a print-optimized layout, entry listing with date/time handling, total entries summary, a print button, and a friendly fallback when no entries are found.
Display the saved creation timestamp (including time) across notes list, note view, and edit form. Adds a human-readable "Saved" line in application/views/notes/edit.php and application/views/notes/view.php, and updates application/views/notes/main.php to include the time using the format "M d, Y \a\t g:i A". The date input in the edit form still uses a YYYY-MM-DD value for the date picker, and entries with empty or zero dates show "N/A".
Updated the logic to display 'N/A' for invalid or empty created_at values, including the '0000-00-00 00:00:00' placeholder, ensuring more accurate date representation in the notes view.
Introduces a migration to add a created_at timestamp to the notes table. Updates the Note model and Notes controller to support filtering notes by creation date, and enhances the notes view to include date filter fields and display the created date for each note. Migration version is incremented to 242.
Introduces note categories with support for filtering, assigning, and managing categories. Adds category selection and creation to add/edit forms, category filtering to the notes list, and modals for deleting/merging categories and confirming note deletion. Updates controller and model logic to handle categories, and improves UI for notes management.
