Track and return whether any QSOs were actually uploaded to Clublog and log/report when none are pending. index(): introduced $uploaded_any_qsos and aggregate per-user upload results; if nothing uploaded, echo a message and write an info log. uploadUser(): return false on invalid Clublog username (was previously void); added $uploaded_for_user tracking while iterating station profiles and set it when Clublog responds with 'accepted'. uploadUser now returns true when QSOs were uploaded for the user, otherwise false.
Use FCPATH to build the upload file path and fall back to DOCUMENT_ROOT plus the configured install directory if the file is missing. Normalizes leading/trailing slashes and casts values to strings to avoid notices, and checks file existence before attempting the fallback. This improves robustness when the app is installed in a subdirectory or when DOCUMENT_ROOT is not set.
Enforces that Clublog usernames are valid email addresses throughout the application, reflecting Clublog's policy change to no longer accept callsigns as usernames. Updates validation in controllers, models, and views, adds a migration to clear non-email usernames, and updates language files in multiple languages to clarify the requirement.
This commit has some further changes to text throughout the application. There are also some small fixes for text formatting. E.g. making sure that the small "helper" text under certain form fields is all consistent in terms of colour, font, etc.
Change the URL for collecting Club Log's cty.xml definitions to use https://cdn.clublog.org (Content Delivery Network, faster). Remove reference to secure.clublog.org and update string "Clublog" to be "Club Log".
Getting my hands dirty for the first time so very minor stuff!
