[CS] Add intents for locks

[adamjez]

Add following intents for lock domain:

• HassTurnOn
• HassTurnOff
• HassGetState

Notes

• The state responses use the terms "Odemčeno" and "Zamčeno", consistent with Home Assistant's terminology for the lock domain.
• The terms "Odemči" and "Zamči" are also accepted, even though they are not grammatically correct.
• While functional, the responses for HassGetState could benefit from refinement to improve natural language output. For example, the sentence:

"Ne, vstupní dveře není zamčeno"

is grammatically awkward and should be revised to:

"Ne, vstupní dveře jsou zamčené."
