Replace legacy apply plugin usage

[andreia-ferreira]

This PR migrates module plugin declarations from the legacy apply plugin syntax to the modern plugins {} block using version catalog aliases. This fixes issues where updating gradle plugin, builds started failing during manifest merging : #3720 and #3708

The issue appears to be related to plugin evaluation order: with the legacy plugin style, the secrets gradle plugin was not being applied early enough, so manifest placeholders were not populated in time which caused manifest merge failures. According to the official docs, wiith the new approach, the plugin resolution happens earlier which ensures the secrets plugin is available before manifest processing.
