ARTFISH Species - Shiny Server Module — artfish_shiny_species

Server-side logic for the ARTFISH Species dashboard.

The *"Catch and effort - Detailed by species"* module provides a species-oriented workspace for exploring key output metrics derived from artfish_compute_report, with a focus on individual species caught.

The initial view displays a selector inviting the user to choose a species. The dropdown lists all species for which entries are available in the database. Users can then analyse the evolution of fishing activity over time, with filtering options for species, fishing units, and time range.

The module is composed of:

A selector panel to choose the species to display
A selector panel to adjust the time range and fishing units to display
Two boxed plots powered by fdishinyr::generic_chart allowing users to analyse, at species level:
- (1) Fishing unit composition (by quantity)
- (2) Target species ranking (by quantity)
A set of KPIs presenting aggregated metrics for the selected period
Five boxed plots powered by fdishinyr::generic_chart allowing users to analyse key Artfish metrics:
- (1) Total catch estimation
- (2) Catch per unit effort (CPUE)
- (3) Total value estimation
- (4) Average price
- (5) Total nominal effort
