## Summary by CodeRabbit
* **Bug Fixes**
* Improved app manifest retrieval with automatic fallback to hosted
copies when the primary source is unavailable, reducing sync failures.
* **Documentation**
* Clarified that Fleet will fall back to hosted manifest copies if the
new manifest site is inaccessible.
* **New Features**
* Streamlined maintained-app synchronization to use a simpler sync
entrypoint and unified primary/fallback fetch logic.
* **Tests**
* Added comprehensive tests for primary/fallback fetch flows, error
handling, large-response truncation, and environment-based overrides.

## Summary by CodeRabbit
* **Refactor**
* Standardized logging to Go's structured slog across MDM (Apple,
Windows), DEP/ABM flows, maintained app sync, and related
tests—improving log consistency and contextual diagnostics without
changing user-facing behavior.

Resolves#38484. This includes a CI job change to make sure we don't
introduce any more env vars that don't get proxied (and thus turned off
outside `--dev`).

Manual QA touched hot paths, but did _not_ manually test every
FLEET_DEV_* environment variable change.
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
* **New Features**
* Centralized dev-mode environment management for consistent FLEET_DEV_*
handling and test-friendly overrides.
* Dev-mode allows targeted overrides for certain dev-only configuration
when running with --dev.
* **Chores**
* Migrated environment access to the centralized dev-mode helper across
the codebase.
* Added CI checks to enforce proper usage of FLEET_DEV_* variables.
* **Documentation**
* Added guidance on dev-mode environment variable rules and overrides.

- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements)
- [x] If paths of existing endpoints are modified without backwards
compatibility, checked the frontend/CLI for any necessary changes
- [x] If database migrations are included, checked table schema to
confirm autoupdate
- For database migrations:
- [x] Checked schema for all modified table for columns that will
auto-update timestamps during migration.
- [x] Confirmed that updating the timestamps is acceptable, and will not
cause unwanted side effects.
- [x] Ensured the correct collation is explicitly set for character
columns (`COLLATE utf8mb4_unicode_ci`).
- [x] Added/updated automated tests
- [x] A detailed QA plan exists on the associated ticket (if it isn't
there, work with the product group's QA engineer to add it)
- [x] Manual QA for all new/changed functionality
