Give a lamp's modes a page: the effects, palettes, presets, speed and intensity of a WLED behind its colour card, with a drum picker and the effect's name on the tile (0.2.83)

Browse Source 
A light that offers effects gets a sparkles key at the top right of its colour
card. It opens a page with a row per thing the lamp offers, all from Home
Assistant: the light's effect and the select entities of its device (a WLED's
colour palette, preset and playlist) with what they are set to, and a slider per
number entity of the device (speed, intensity). Names are Home Assistant's own
English entity translations, icons its frontend's; nothing about a brand is
hardcoded beyond a preferred order of translation keys.

A row opens LVGL's roller with every name Home Assistant lists at that moment,
asked for when the picker opens (esphome.screen_options, answered with
op: options, one page of names per message), the effects alphabetically with
Solid on top. The check key at the top right sends the choice as one action;
the back key sends nothing. A slider sends number.set_value when let go. While
an effect runs, the tile names it instead of the brightness.

Firmware 0.2.70: effects_page.h (built when it opens, gone when it closes),
Extra.effect/option_rows/number_rows, options_request, a hidden roller widget
so ESPHome compiles LVGL's roller, five firmware-only glyphs. App 0.2.83:
light_effects.py, the effect attribute, the device rows in the state message,
card_options_loop. Checked on the host with a virtual finger (35/35 on both
boards) and compiled for both ESP32 boards; CYD 1,675,424 B (91.3 %).
