Chore/bugfix refactor

• added color schemes for status in tables;
• enriched dictionaries;
• made button styles universal;
• added a fallback in case there are 0 results in the table (Нажаль, ви ще не створили...);
• refactored links everywhere so that they go by name, not by url;
• added functionality to pagination for handling non-existent parameters (page=-1, page=9999, page=sdsfs);
• made minor fixes in the design
