[UX] address user feedback: per-year template text and column header, more visible "Add resource" button, fixed next-tab navigation on all pages, updated method constraints intro text
[REFACTOR] tab3: relocate normalize_costs, get_slider_params, is_method_enabled, is_custom_secondary to data_utils; show summary table even when no active method
[DOCS/FIX] First draft of Objective No. 5: TO FACILITATE MAINTENANCE AND UPDATES FOR CG STAFF. (No more hard-coded settings, libraries updated, instructions added to the README)
[FEAT] Goal 1 almost achieved: two types of limits possible(percentage / absolute value), start of unit conversion, adapted export templates and a bug fix in the ‘Coefficients’ tab (some resources not displayed)
[FEAT] Possibility to choose between running the optimization with manually entered values or by adding a pre-existing scenario (JSON) -> in this case, the values are automatically populated in all other input tabs
[FIX] Terminal warnings: "DataFrame.applymap has been deprecated" and "`label` got an empty value." + Bug: Value change not applied on the second change (slider coefficient in tab 3 and numeric value in tab 1)
