Refactor: Consolidate and standardize generator logic

[AnouarMohamed]

Description

The current generator structure is split across multiple files with inconsistent naming and redundant logic. Specifically, angular.py/scaffold_angular.py and spring.py/scaffold_spring.py share similar Jinja2 setup and configuration patterns.

Tasks

1. Consolidate Generators: Merge initialization and scaffolding logic for each framework into unified modules (e.g., devctl/generators/angular/).
2. Standardize Naming: Fix the confusion between 'init' and 'scaffold' by using consistent terminology.
3. Centralize Template Management: Create a shared utility or class to handle Jinja2 environment setup to avoid path duplication across multiple files.

Affected Files

• devctl/generators/angular.py
• devctl/generators/scaffold_angular.py
• devctl/generators/spring.py
• devctl/generators/scaffold_spring.py
