refactor(@schematics/angular): add trailing commas and remove leading commas in component template

Added trailing commas to all component metadata properties in the schematic template
to ensure cleaner diffs and consistent formatting. Removed unnecessary leading commas
from conditional blocks since each property now ends with a trailing comma.

(cherry picked from commit a660d69)
