i18n(epg): translate multi-EPG toolbar tooltips

The Zoom/Filter/Search Programs buttons in the Multi-EPG header
hard-coded English matTooltip strings, so they never localized — even
when the rest of the toolbar (Close, Previous/Next day) used keys. Adds
six new EPG.* keys (ZOOM_IN, ZOOM_OUT, FILTER_CHANNELS, CLOSE_FILTER,
SEARCH_PROGRAMS, CLOSE_PROGRAM_SEARCH), wires both [matTooltip] and
[attr.aria-label] through `| translate`, and fans the strings out to
all 17 non-English locales via the i18n-fill pipeline.
