c990da265a Add unit tests for FlashStringLiteral 
Cover the three lines reported uncovered by codecov in
cpp_generator.py (FlashStringLiteral.__init__ and __str__).

91487e7f14 [api] Store HomeAssistant action strings in PROGMEM on ESP8266 
On ESP8266, .rodata is copied to RAM at boot. Every string literal in
HomeAssistantServiceCallAction (service names, data keys, data values)
permanently consumes RAM even though the action may rarely fire.

Add FLASH_STRING type to TemplatableValue that stores PROGMEM pointers
on ESP8266 via the existing __FlashStringHelper* type. At play() time,
strings are copied from flash to temporary std::string storage — safe
because service calls are not in the hot path.

Add FlashStringLiteral codegen helper (cg.FlashStringLiteral) that wraps
strings in ESPHOME_F() — expands to F() on ESP8266 (PROGMEM), plain
string on other platforms (no-op). This helper can be adopted by other
components incrementally.

On non-ESP8266 platforms, FLASH_STRING is never set and all existing
code paths are unchanged.
