[core] Defer requests import in external_files and web_server_ota

Same pattern as framework_helpers: both modules imported requests at module top level but only use it inside functions that perform actual network I/O (downloading fonts/images, web_server OTA upload), never during config validation. external_files is loaded by the font and audio_file components. Defer the imports into the functions that use them, and update the tests to patch requests.<method> directly (the modules no longer hold a requests attribute). Adds regression tests guarding against re-introducing the top-level imports.

-            Heads up: the legacy ESPHome dashboard (\`esphome/dashboard/\` and \`tests/dashboard/\`) is **deprecated** and is being replaced by [ESPHome Device Builder](https://github.com/esphome/device-builder). We are not adding new features to the legacy dashboard and it will eventually be removed from this repository.
-
-            What this means for your PR:
-
-            - **New features / enhancements**: please port the change to [esphome/device-builder](https://github.com/esphome/device-builder) instead. We are unlikely to review or merge new dashboard features here.
-            - **Bug fixes**: small fixes may still be considered, but please check first whether the same issue exists in Device Builder, where the fix will have a longer life.
-            - **Security issues**: please do not file a public PR. Report privately via [GitHub security advisories](https://github.com/esphome/esphome/security/advisories/new) so we can coordinate a fix.
-
-            We appreciate the contribution and apologize for the friction; flagging this early so your time isn't spent on a change that may not land.

        If you need a real-world example, search for components that use `@dataclass` with `CORE.data` in the codebase. Note: Some components may use `TypedDict` for dictionary-based storage; both patterns are acceptable depending on your needs.

Franck Nijhof	19280e03ad	[core] Defer requests import in external_files and web_server_ota Same pattern as framework_helpers: both modules imported requests at module top level but only use it inside functions that perform actual network I/O (downloading fonts/images, web_server OTA upload), never during config validation. external_files is loaded by the font and audio_file components. Defer the imports into the functions that use them, and update the tests to patch requests.<method> directly (the modules no longer hold a requests attribute). Adds regression tests guarding against re-introducing the top-level imports.	2026-06-25 20:42:35 +00:00
Franck Nijhof	1ff519446b	[core] Guard deferred requests import and fix download test patch targets Add a regression test asserting framework_helpers does not import requests at module import time, and update the download_from_mirrors tests to patch requests.get directly (the module no longer holds a requests attribute now that the import is deferred into the function).	2026-06-25 19:04:41 +00:00
Franck Nijhof	ee1fffb062	[core] Defer requests import in framework_helpers framework_helpers imported requests at module top level, but it is only used by download_from_mirrors() to fetch toolchains during a build. The module is loaded during config validation (via the esp-idf framework, the default for esp32, and the host platform), so every such config paid the ~85ms requests import cost even though validation never downloads anything. Defer the import into download_from_mirrors(). Measured roughly 70ms (~16%) off esphome config wall time for an esp-idf/host config.	2026-06-25 18:51:48 +00:00
